[0001] The utility model relates to the technical field of vehicle parts, and in particular to a fender mounting structure, a vehicle body assembly and a vehicle. Background Art

[0002] Currently, fenders are styling components at the front end of a car, typically mounted on the side panels of the vehicle body. Furthermore, fenders typically have two mounting points: the upper mounting point is typically located on the side panel pillar, while the lower mounting point is typically located on the side panel sill.

[0003] In the prior art, pre-embedded rivet nuts are usually used on the side sills of the sheet metal structure as the lower mounting point of the fender. The fender is fixed by fixing the lower end of the fender to the outer panel of the side sill. However, this method requires adding side punching holes to the outer panel of the side sill, which requires the cross-section of the cavity at the bottom of the sheet metal sill to be increased in the vertical direction of the car (i.e., the Z direction), for example, to reach more than 85mm, and the dimension in the left and right direction of the car (i.e., the Y direction) needs to be minimized to meet the mold strength and draw formability of the side punching holes, which imposes significant constraints on the styling. Moreover, adding side punching holes will also lead to an increase in the stamping die cost and processing cost of the side outer panel, which in turn leads to a higher production cost of the side outer panel.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The fender mounting structure of the present invention achieves fender mounting by providing mounting brackets and connecting, for example, the upper and lower ends of the fender to the outer panel body of the side panel and the mounting brackets, respectively. Furthermore, by connecting the mounting brackets to the inward-facing side of the side panel sill beam, such as by welding, the mounting brackets are used to securely connect, for example, the lower end of the fender to the side panel sill beam, thereby eliminating the need to directly secure the lower end of the fender to the side panel sill beam. This eliminates the need for punched holes in the side panel sill beam for fender mounting, allowing the Z-direction dimension of the cavity beam structure, for example, at the lower portion, to be reduced while maintaining strength, thereby reducing constraints on vehicle styling. Furthermore, by eliminating the need to punch fender mounting holes in the side panel, the structure of the side panel stamping die can be simplified, reducing the number of processing steps required, and thus reducing the cost of the stamping die and processing, and thus, the production cost, of the side panel. In addition, arranging the mounting bracket on the side of the door sill beam facing the interior of the vehicle can reduce the space occupied by the fender mounting structure composed of the side outer panel and the mounting bracket, making it easier to arrange the entire vehicle.

Therefore, they should not be understood as limiting the present invention.

[0032] It should be noted that the terms "first," "second," and the like in the specification and claims of the present invention and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, such that the embodiments of the present invention described herein can be implemented in an order other than that illustrated or described herein.

[0033] Combine Figure 1 、 Figure 2 and Figure 3 As shown, an embodiment of the present invention provides a fender mounting structure, including a side outer panel 1 and a mounting bracket 2, the side outer panel 1 includes an outer panel body 11 and a door sill beam 12 connected in an integral manner, the mounting bracket 2 is connected to the side of the door sill beam 12 facing the interior of the vehicle, and the mounting bracket 2 and the outer panel body 11 are respectively used to connect with the fender 600.

[0034] Specifically, a side panel 1 is usually provided on each of the left and right sides of the vehicle (i.e., both sides of the vehicle along the Y-axis direction), and the two side panels 1 are symmetrically arranged. Figure 1and Figure 3 The side outer panel 1 shown in the figure is the side outer panel 1 on the left side of the vehicle. More specifically, the side outer panel 1 is usually a sheet metal part and mainly includes two parts, namely the outer panel body 11 and the door sill beam 12, and the door sill beam 12 is provided at the lower end of the outer panel body 11, wherein the outer panel body 11 is usually composed of a plurality of columns such as A-pillars, B-pillars, and C-pillars, and the lower part of the door sill beam 12 is usually a cavity beam structure, and the front and rear ends of the cavity beam structure (that is, the two ends of the cavity beam structure in the X-axis direction) and the side facing the interior of the vehicle are usually open, that is, the cross section of the cavity beam structure (that is, the cross section of the cavity beam structure along the direction perpendicular to the Figure 1 The cross section (in the mid-X-axis direction) generally presents a semi-enclosed structure. The outer panel body 11 and the sill beam 12 may be integrally connected by welding. In this case, the outer panel body 11 and the sill beam 12 are manufactured separately and then assembled by welding to form the side outer panel 1. The outer panel body 11 and the sill beam 12 may also be integrally connected by integral molding. In this case, the entire side outer panel 1 is typically integrally formed by a stamping process. The mounting bracket 2 is a bracket structure for mounting the fender 600. It is usually connected to the lower front end of the sill beam 12 (i.e., the lower end of the sill beam 12 located in the positive direction of the X-axis) by means of welding, and is located on the inner side of the sill beam 12, i.e., the side of the sill beam 12 facing the inside of the vehicle. Taking the left door of the vehicle as an example, the inside side is the right side, i.e., the opposite direction of the Y-axis, and the outside side is the left side, i.e., the positive direction of the Y-axis. That is to say, for the left side outer panel 1, the side of the sill beam 12 facing the inside of the vehicle is the right side of the sill beam 12, and correspondingly, the side of the sill beam 12 facing the outside of the vehicle is the left side of the sill beam 12. Furthermore, the lower mounting point of the fender 600 (i.e., mounting structures such as rivet nuts) is typically provided on the mounting bracket 2, eliminating the need for side punching holes in the sill beam 12 of the side outer panel 1 for mounting the fender 600. This reduces the number of stamping steps for the side outer panel 1 from five to four, and reduces the cost of the stamping mold by approximately RMB 2-3 million. Furthermore, since side punching holes are not required in the sill beam 12, the cavity structure below the sill beam 12 can be significantly reduced in the Z-direction while ensuring mold strength and meeting styling requirements. In actual production, this can be reduced by approximately 50-60 mm. During installation, the upper end of the fender 600 is typically removably secured to a pillar (e.g., an A-pillar) of the outer panel body 11, while the lower end of the fender 600 is removably secured to the mounting bracket 2, thereby achieving the installation and fixation of the fender 600.

[0035] The fender mounting structure in this embodiment can be secured by providing a mounting bracket 2 and connecting, for example, the upper and lower ends of the fender 600 to the outer panel body 11 of the side outer panel 1 and the mounting bracket 2, respectively, to achieve securement of the fender 600. Furthermore, by connecting the mounting bracket 2 to the inward-facing side of the sill beam 12 of the side outer panel 1, such as by welding, the mounting bracket 2 is used to securely connect, for example, the lower end of the fender 600, thereby avoiding the need to directly secure the lower end of the fender 600 to the sill beam 12 of the side outer panel 1. This eliminates the need to add side punching holes to the sill beam 12 of the side outer panel 1 for mounting the fender 600. This allows the Z-direction dimension of the sill beam 12, for example, its lower cavity beam structure, to be reduced while maintaining strength, thereby reducing constraints on the vehicle's styling. Furthermore, since the fender mounting holes are no longer stamped on the side panel 1, the structure of the stamping die for the side panel 1 can be simplified, reducing the number of processes required to manufacture the side panel 1. This reduces both the die and processing costs for the side panel 1, and consequently, the production cost of the side panel 1. Furthermore, positioning the mounting bracket 2 on the inward-facing side of the sill beam 12 reduces the space occupied by the fender mounting structure formed by the side panel 1 and the mounting bracket 2, facilitating overall vehicle layout.

[0036] Furthermore, the side outer panel 1 is a sheet metal part and is integrally formed using a stamping process.

[0037] Because the assembly process for the plastic rocker beam 12 is complex and the production cost is high, in this embodiment, the side panel 1 is constructed from sheet metal to reduce production costs and simplify the assembly process for the rocker beam 12. Furthermore, the use of an integrated molding process for the side panel 1 reduces the number of parts, easing assembly complexity and ultimately improving production efficiency.

[0038] Optionally, combined Figure 2 and Figure 6 As shown, a notch 121 is provided at the end of the door sill beam 12 , and the mounting bracket 2 is provided at the notch 121 .

[0039] In this embodiment, since the fender 600 is typically mounted on the front side of the rocker beam 12, a notch 121 is typically provided at the lower front end of the rocker beam 12, and the mounting bracket 2 is positioned within this notch 121. The notch 121 is typically positioned toward the interior of the vehicle to avoid being visible and affecting the vehicle's appearance. This further reduces the space occupied by the fender mounting structure and, while reducing the weight of the rocker beam 12 and, more importantly, the side panel 1, utilizes the mounting bracket 2 to enhance the structural strength of the rocker beam 12 at the notch 121. This ensures the structural strength of the rocker beam 12 and the side panel 1, while also facilitating a lightweight design for the entire vehicle.

[0040] Optionally, combined Figure 2 and Figure 4 As shown, a connecting member 5 is provided on the mounting bracket 2 , and the connecting member 5 is used to fix the fender 600 .

[0041] In this embodiment, the mounting bracket 2 is typically provided with a fixing hole 221, and the connector 5 is typically located at the fixing hole 221. The connector 5 provided on the mounting bracket 2 may be a rivet nut. In this case, the rivet nut is typically pre-embedded in the mounting bracket 2, allowing the fender 600 to be secured using the rivet nut in conjunction with a bolt. The connector 5 may also be a snap-fit ​​structure, in which case the fender 600 can be secured to the mounting bracket 2 by snap-fitting. In practical applications, the design can be selected as needed. In this way, the connector 5 is used to achieve a detachable fixed connection between the fender 600 and the mounting bracket 2, resulting in a simple structure and easy processing and manufacturing.

[0042] Optionally, combined Figure 1 、 Figure 5 and Figure 9 As shown, the fender mounting structure further includes a column connecting plate 3, which is connected to the side of the door sill beam 12 facing the interior of the vehicle, and the mounting bracket 2 is connected to the side of the column connecting plate 3 facing the front direction of the vehicle. Figure 1 The positive direction of the middle X axis, correspondingly, the rear direction of the vehicle is Figure 1 The X axis is reversed.

[0043] In this embodiment, the pillar connecting plate 3 is typically an A-pillar connecting plate, which is typically connected to the sill beam 12 and the mounting bracket 2 by welding. Specifically, the pillar connecting plate 3 is typically a bent plate-shaped structure, with one end of the pillar connecting plate 3 in the left-right direction typically welded to the inner side of the sill beam 12, and the front end of the pillar connecting plate 3 typically welded to the rear end of the mounting bracket 2. Thus, by connecting the sill beam 12 and the mounting bracket 2 to the pillar connecting plate 3, the rigidity of the fender 600's lower mounting point is not only improved, but the load borne by the mounting bracket 2 and the sill beam 12 is also shared by the pillar connecting plate 3, thereby improving the load-bearing capacity of the sill beam 12 and the mounting bracket 2, thereby accommodating the installation and fixation of fenders 600 of different specifications.

[0044] Optionally, combined Figure 1 、 Figure 5 and Figure 9 As shown, the fender mounting structure further includes a pillar reinforcement plate 4 located on the side of the pillar connecting plate 3 facing the interior of the vehicle, and the pillar reinforcement plate 4 is connected to the side outer panel 1 and the pillar connecting plate 3 .

[0045] In this embodiment, the pillar reinforcement plate 4 is typically an A-pillar reinforcement plate, which is typically welded to the side outer panel 1 and the pillar connecting plate 3. Specifically, the pillar reinforcement plate 4 is also typically a bent plate-like structure and is located on the side of the side outer panel 1 facing the interior of the vehicle. Furthermore, the upper half of the pillar reinforcement plate 4 is typically welded to the inner side of the outer panel body 11, while the lower half is typically welded to the inner side of the pillar connecting plate 3. In other words, the pillar connecting plate 3 is sandwiched between the pillar reinforcement plate 4 and the side outer panel 1. This creates a three-layer overlap structure between the side outer panel 1, the pillar connecting plate 3, and the pillar reinforcement plate 4, further enhancing the local structural strength of the side outer panel 1 at the sill beam 12 and ensuring the stability of the fender 600 fixed to the sill beam 12 via the mounting bracket 2.

[0046] Optionally, combined Figure 2 、 Figure 7 and Figure 8 As shown, the mounting bracket 2 includes a first connecting portion 21 and a second connecting portion 22 connected to each other, and the second connecting portion 22 is located above the first connecting portion 21. The first connecting portion 21 is connected to the pillar connecting plate 3, and the second connecting portion 22 is connected to the door sill beam 12 and is used to connect to the fender 600.

[0047] In this embodiment, the first connecting portion 21 and the second connecting portion 22 are typically plate-like structures, serving as the rear and upper panels of the mounting bracket 2, respectively. In other words, the mounting bracket 2 is a bent plate-like structure. Furthermore, the fixing holes 221 are typically located on the upper panel of the mounting bracket 2, i.e., the second connecting portion 22. During installation, the lower portion of the fender 600 is removably secured to the upper panel of the mounting bracket 2 via the connector 5. The sill beam 12 is welded to the upper panel of the mounting bracket 2, while the pillar connecting plate 3 is welded to the rear panel of the mounting bracket 2. This achieves connections between the sill beam 12 and the mounting bracket 2, and between the pillar connecting plate 3 and the mounting bracket 2, respectively. This provides a simple structure and facilitates installation.

[0048] Optionally, combined Figure 2 、 Figure 7 and Figure 8 As shown, the mounting bracket 2 further includes a third connecting portion 23, the first connecting portion 21, the second connecting portion 22 and the third connecting portion 23 are connected in sequence, the first connecting portion 21 and the third connecting portion 23 are arranged opposite to each other along the front-to-rear direction of the vehicle and are located below the second connecting portion 22, and a lap portion 122 is provided at one end of the sill beam 12 along the front-to-rear direction of the vehicle, the lap portion 122 is provided on the side of the sill beam 12 facing the interior of the vehicle and overlaps with the third connecting portion 23.

[0049] It should be noted that the front and rear directions of the vehicle are Figure 1 The X-axis direction is referred to as the front-to-back direction. Correspondingly, the left-to-right direction of the vehicle is Figure 1The Y-axis direction is referred to as the left and right direction, and the up and down direction of the vehicle is Figure 1 The middle Z-axis direction, referred to as the up and down direction.

[0050] In this embodiment, the third connecting portion 23 is also typically a plate-shaped structure, and the third connecting portion 23 and the second connecting portion 22 serve as the front and rear side panels of the mounting bracket 2, respectively. Furthermore, an overlapping portion 122 is provided on the inner side of the front end of the sill beam 12. During installation, by connecting the overlapping portion 122 to the front side panel of the mounting bracket 2, i.e., the third connecting portion 23, by welding, for example, the mounting bracket 2 is connected to the sill beam 12 of the side outer panel 1 in the vehicle's front-to-back direction (i.e., the X-direction), further ensuring the secure connection between the mounting bracket 2 and the sill beam 12.

[0051] Optionally, combined Figure 2 and Figure 7 As shown, the third connecting portion 23 is provided with a mounting hole 231 for mounting the fender 700 , and the mounting hole 231 passes through the third connecting portion 23 along the front-rear direction of the vehicle.

[0052] In this embodiment, the mounting hole 231 on the third connecting portion 23 serves as the lower mounting hole for the fender 700. Accordingly, a connecting hole structure similar to the mounting hole 231 is typically provided on the fender 600, serving as the upper mounting hole for the fender 700. The mounting hole 231 extends through the third connecting portion 23 along the X-axis, and the connecting hole structure on the fender 600 also typically extends through the fender 600 along or substantially along the X-axis. The mounting hole 231 can be a bolt hole, in which case the fender 700 is secured to the third connecting portion 23 of the mounting bracket 2 via bolts. Alternatively, the mounting hole 231 can be a slot, in which case the fender 700 is secured to the third connecting portion 23 via a snap-fit ​​mechanism. During installation, the upper mounting hole of the fender 700 is typically installed along the X-axis or slightly tilted relative to the X-axis, while the lower mounting hole of the fender 700 is also installed along the X-axis. In this way, by providing a mounting hole 231 on the third connecting portion 23 of the mounting bracket 2, a mounting point is provided for the lower portion of the fender 700 on the mounting bracket 2. At the same time, the mounting hole 231 is set to pass through the third connecting portion 23 along the front-to-rear direction of the vehicle, so that the lower mounting hole of the fender 700 can also be connected to the mounting bracket 2 along the X-axis direction, ensuring that the installation directions of the upper mounting hole and the lower mounting hole of the fender 700 are basically consistent. In this way, when the fender 700 is matched with the vehicle body structure, it can be adjusted by slightly moving up and down to adapt to the tolerance of the vehicle body structure in the Z direction (i.e., the up and down direction). Moreover, it can also ensure that the gap between the installed fender 700 and the rocker beam 12 of the side outer panel 1 in the Y direction (i.e., the left and right direction) is uniform, thereby improving production quality.

[0053] Combine Figure 9and Figure 10 As shown, another embodiment of the present invention provides a vehicle body assembly, including a fender 600, a mudguard 700 and the fender mounting structure as described above, wherein the upper end of the fender 600 is connected to the side outer panel 1 of the fender mounting structure, and the lower end of the fender 600 and the mudguard 700 are respectively connected to the mounting bracket 2 of the fender mounting structure.

[0054] In this embodiment, the fender 700 is typically a front wheel fender. It is not only connected to the mounting bracket 2 but also removably connected to the fender 600. Furthermore, the fender 700 is disposed correspondingly to the fender 600, which in turn is disposed correspondingly to the side panel 1. Specifically, the lower end of the fender 600 on the left side of the vehicle is mounted to the sill beam 12 of the left side panel via the left mounting bracket 2, and the left front wheel fender is secured to the front end of the mounting bracket 2 using a fastener such as a clip. The lower end of the fender 600 on the right side of the vehicle is mounted to the sill beam 12 of the right side panel via the right mounting bracket 2, and the right front wheel fender is secured to the front end of the mounting bracket 2 using a fastener such as a clip. Furthermore, the vehicle body assembly of this embodiment has the same beneficial effects as the fender mounting structure described above relative to the prior art and will not be further described here.

[0055] Another embodiment of the present invention provides a vehicle, including the fender mounting structure described above, or including the vehicle body assembly described above.

[0056] The beneficial effects of the vehicle in this embodiment relative to the prior art are the same as those of the above-mentioned fender mounting structure, and will not be described in detail here.

[0057] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
