[0008] As an alternative implementation, the connector extends along the side length of the rear floor.

[0009] With this configuration, the connector can be attached from the side to the inner panel of the rear wheel arch and the rear floor, extending the connection length and increasing the connection strength.

[0011] This design increases the contact area of ​​the connection points, reduces localized stress concentration, and improves connection strength and fatigue life.

[0012] As an optional implementation, the first connecting part and the second connecting part are integrally molded parts.

[0013] This design avoids increasing the number of connection points, thereby improving the overall strength of the rear wheel arch assembly.

[0019] With this configuration, the rear floor, connected to the reinforcement and the inner plate of the rear wheel arch via two extension sections, can disperse stress and improve vibration reduction.

[0020] As an optional implementation, there are multiple connectors, which are spaced apart along the lower edge of the inner plate of the rear wheel arch.

[0023] This configuration, with two connectors and two reinforcing members, can distribute the dynamic load, reduce the stress at individual connection points, and extend fatigue life.

[0024] Secondly, this application provides a vehicle including a rear floor and the aforementioned rear wheel arch assembly, the rear wheel arch assembly being connected to the rear floor.

[0040] With the rapid development of automotive lightweighting technology, aluminum alloy castings are increasingly widely used in vehicle body structures. Compared with traditional steel structures, aluminum alloy castings have advantages such as lightweight and high performance, which can effectively reduce the weight of the entire vehicle while meeting the requirements of body rigidity and strength.

[0041] In the existing technology, the rear floor of some vehicle models is made of aluminum alloy castings. The aluminum alloy rear floor is mainly formed by high pressure casting process, which can realize the integrated design of complex structures and reduce the number of parts and assembly processes.

[0042] However, due to the differences in body size among different car models, traditional casting processes cannot meet the needs of multiple models with a single mold. Aluminum alloy casting molds are expensive. Currently, car manufacturers and factories generally reduce the cost per unit through mass production. How to make a cast aluminum rear floor adaptable to car models of different lengths and widths is a challenge.

[0043] To address the aforementioned technical problems, this application provides a rear wheel arch assembly and vehicle, which connects the rear wheel arch and cast aluminum rear floor using connecting plates of different models and specifications. This allows the cast aluminum rear floor of the same size to be applicable to different vehicle models, reducing production costs.

[0044] This application provides a rear wheel arch assembly and a vehicle. The vehicle in this application can refer to a large car, a small car, a special vehicle, etc. For example, according to the vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other vehicle types that use a cast aluminum rear floor.

[0045] Figure 1 A schematic diagram of the installation structure of the rear wheel arch assembly and rear floor provided in the embodiments of this application; Figure 2 Exploded view of the rear wheel arch assembly and rear floor provided in the embodiments of this application; Figure 3 for Figure 1 Schematic diagram of the AA section; Figure 4 for Figure 1 Schematic diagram of the BB cross section.

[0046] See Figure 1 and Figure 2This application provides a rear wheel arch assembly 100 for a vehicle. The rear wheel arch assembly 100 includes a rear wheel arch inner plate 110, a connector 120, and a reinforcing member 130. The rear wheel arch inner plate 110 is located on the side of the rear floor 200 of the vehicle. The connector 120 is connected to the rear wheel arch inner plate 110 and the rear floor 200. The reinforcing member 130 is connected to the side of the rear wheel arch inner plate 110 facing the rear floor 200, and the lower edge of the reinforcing member 130 is connected to the rear floor 200. The lower edge of the reinforcing member 130 is provided with an overlapping structure 133, which abuts against the upper edge of the side of the rear floor 200.

[0047] It should be noted that the rear wheel arch assembly 100 is located at the rear of the vehicle side panel assembly. The rear wheel arch inner panel 110 is a structural load-bearing component of the rear wheel arch assembly 100, connected to the rear floor 200 of the vehicle, used to bear mechanical loads, and can also transmit vibrations and absorb the impact force of collisions. The rear wheel arch inner panel 110 is connected to the rear floor 200 through a connector 120. The shape and size of the connector 120 can be designed according to the edge contours and spacing of the rear wheel arch inner panel 110 and the rear floor 200 to adapt to different... The rear wheel arch assembly 100 also includes a rear wheel arch outer plate 140, which is located outside the rear wheel arch inner plate 110. The rear wheel arch outer plate 140 covers the rear wheel area and can prevent mud, gravel and other foreign objects from splashing into the vehicle body, reducing the risk of damage to chassis components. The rear floor 200 is an aluminum alloy casting and can be integrally cast using a single mold. The mold size can be determined according to the smallest vehicle model. The lower side of the reinforcing member 130 is connected to the rear floor 200, and the upper side is connected to the rear wheel arch inner plate 110.

[0048] Before the rear wheel arch inner panel 110 is connected to the rear floor 200, the connector 120 can be connected to the rear floor 200 first. The connector 120 and the rear floor 200 can be connected via SPR (Self-Piercing). Riveting (self-piercing riveting) can be used for connection, or welding can be used for connection. The upper side of the reinforcing member 130 and the inner plate 110 of the rear wheel arch can be welded or riveted first. Before connecting the inner plate 110 of the rear wheel arch to the connecting member 120, the overlapping structure 133 of the reinforcing member 130 can be overlapped on the side edge of the rear floor 200. This allows the side edge of the rear floor 200 to provide support for the reinforcing member 130 and the rear wheel arch through the overlapping structure 133, which can reduce the tooling pressure on the rear wheel arch and prevent the rear wheel arch from falling off during the connection process. This facilitates the connection of the inner plate 110 of the rear wheel arch and the connecting member 120. The inner plate 110 of the rear wheel arch and the connecting member 120 can be connected by one connection method such as welding at the weld point 126, bolt connection, and riveting, or multiple methods can be used simultaneously to increase the connection strength. By using the above-mentioned pre-connection and then overall assembly method, the impact of the aluminum alloy rear floor 200 on the existing production line can be reduced.

[0049] In one possible implementation, the connector 120 extends along the side length of the rear floor 200. The connector 120 is elongated and flat, extending vertically in width and perpendicular to the horizontal plane of the rear floor 200. The width of the connector 120 matches the distance between the rear floor 200 and the inner rear wheel arch panel 110. The length of the connector 120 extends along the side length of the rear floor 200. Both ends of the connector 120 abut against the reinforcement 130, and / or, one end of the connector 120 is located at the edge of the rear wheel arch, and the other end abuts against the reinforcement 130. The connector 120 has an irregular shape, and multiple connectors 120 may have different shapes. The rear wheel arch is made of steel, the rear floor 200 is an aluminum alloy casting, and the connector 120 is made of steel.

[0050] Reference Figure 4 , combined Figure 1 and Figure 2 As one possible implementation, the connector 120 includes a first connecting portion 123 and a second connecting portion 124. The first connecting portion 123 is connected above the second connecting portion 124. The outline shape of the first connecting portion 123 matches the outline shape of the lower edge of the rear wheel arch inner plate 110, and the first connecting portion 123 is connected to the rear wheel arch inner plate 110. The connection method can be welding, riveting, or other methods. The outline shape of the second connecting portion 124 matches the outline shape of the upper edge of the side of the rear floor 200, and the second connecting portion 124 is connected to the rear floor 200. The connection method can be welding, riveting, or other methods.

[0051] It is understood that the first connecting portion 123 and the second connecting portion 124 are located at both ends of the connector 120 in the width direction. Both the first connecting portion 123 and the rear wheel arch inner plate 110 are made of steel and can be reinforced by riveting after welding. The welding method can be resistance spot welding, where pressure and current are applied to the contact points of the first connecting portion 123 and the rear wheel arch inner plate 110 using electrodes. The material resistance heats up and melts the local metal, forming a weld nugget after cooling, thus achieving a mechanical connection. The welding points extend along the length of the connector 120; for example, there can be 3-5 welding points, but this application does not specify a particular number. Simultaneously, bolts are used to reinforce local connections at non-spot welding locations, such as in high-vibration areas. This combination of resistance spot welding and bolts can meet both structural strength and maintainability requirements. Furthermore, adhesive can be used to seal the joints, which can help with sound insulation and vibration reduction of the vehicle body.

[0052] It is understandable that the second connecting part 124 can be riveted to the rear floor 200 in an SPR manner. The second connecting part 124 is parallel to the outer edge of the rear floor 200. The rivet penetrates the steel connecting part 120 and the outer edge of the aluminum alloy rear floor 200 under pressure. Then the tail of the rivet expands in the outer edge of the rear floor 200 to form a mechanical interlock. The rivet is tightly connected to the connecting part 120 and the rear floor 200 to form a high-strength connection.

[0053] In one possible implementation, the first connecting part 123 and the second connecting part 124 are integrally formed parts. The first connecting part 123 and the second connecting part 124 are two parts of the connector 120. The connector 120 is made of steel and can be formed by stamping with a multi-station mold. After the connector 120 is formed, the side that matches the contour shape of the lower edge of the rear wheel arch inner plate 110 forms the first connecting part 123, and the side that matches the contour shape of the upper edge of the side of the rear floor 200 forms the second connecting part 124. The connector 120 needs to be punched and trimmed after forming. Bolt holes need to be pre-drilled in the first connecting part 123. The number of bolt holes can be one, two, three, etc., and this embodiment does not specifically limit the number.

[0054] As one possible implementation, the connector 120 and the reinforcement 130 are located at different positions on the side profile of the rear floor 200.

[0055] Understandably, the connector 120 is used to connect the rear wheel arch inner plate 110 and the rear floor 200 to transfer loads; the reinforcing member 130 is used to enhance local rigidity and can also connect the rear wheel arch inner plate 110 and the rear floor 200. The connector 120 and the reinforcing member 130 are spaced apart at different positions on the side profile of the rear floor 200. The reinforcing member 130 can be installed in high-stress areas. Where no reinforcing member 130 is installed, a connector 120 of a suitable shape is used to connect the rear wheel arch inner plate 110 and the rear floor 200, based on the spacing, profile length, and shape.

[0056] Reference Figure 1 and Figure 2 As one possible implementation, the lower edge of the reinforcing member 130 is provided with a bent portion, which extends relative to the lower edge of the reinforcing member 130 toward the inner side edge of the rear floor 200 to form an overlapping structure 133.

[0057] It should be noted that the reinforcing member 130 can overlap with the upper side edge of the rear floor 200 through the bending part. The overlapping structure 133 provides support when the rear wheel arch inner plate 110 is connected to the connector 120, making it convenient for workers to weld and bolt the rear wheel arch inner plate 110 to the connector 120. If the rear wheel arch inner plate 110 is connected to the connector 120 and the tooling is used to provide support for the rear wheel arch, on the one hand, the tooling pressure is too high, and the rear wheel arch is easy to fall off; on the other hand, it is difficult to align the connection point of the rear wheel arch inner plate 110 and the connector 120, increasing the difficulty of connection.

[0058] Understandably, the bent portion protrudes from the surface of the reinforcing member 130 facing the rear floor 200. The bent portion has a first plane perpendicular to the lower edge of the reinforcing member 130 and a second plane parallel to the lower edge of the reinforcing member 130. The first plane is connected to the lower edge of the reinforcing member 130, and the second plane is connected to the first plane. The second plane forms a gap with the lower edge of the reinforcing member 130. The gap between the second plane and the lower edge of the reinforcing member 130 is greater than the thickness of the upper edge of the side panel of the rear floor 200. When the overlapping structure 133 overlaps the upper edge of the side panel of the rear floor 200, the lower edge of the reinforcing member 130, the first plane, and the second plane form a latch, which is fastened to the upper edge of the side panel of the rear floor 200. The lower edge of the reinforcing member 130 and the second plane are located on both sides of the upper edge of the side panel of the rear floor 200, so that the latch can provide support for the reinforcing member 130. Since the upper side of the reinforcing member 130 is connected to the inner panel 110 of the rear wheel arch, the support can be transmitted to the entire rear wheel arch.

[0059] In some embodiments, provided that the overlapping structure 133 can provide support, the angle between the first plane and the lower edge of the reinforcing member 130 may not be 90°, and the angle between the first plane and the second plane may not be 90°. For example, the angle between the first plane and the lower edge of the reinforcing member 130 may be 80°, 100°, 120°, etc., and the angle between the first plane and the second plane may be 80°, 100°, 120°, etc. The embodiments of this application do not impose specific limitations.

[0060] Reference Figure 3 , combined Figure 1 and Figure 2 As one possible implementation, the lower edge of the reinforcing member 130 is spaced from the inner rear wheel arch panel 110; the side of the rear floor 200 has an upwardly extending first extension 210 and a second extension 220, the first extension 210 is located inside the second extension 220, the first extension 210 is connected to the lower edge of the reinforcing member 130 by a fastener 134, and the second extension 220 is bonded to the lower edge of the inner rear wheel arch panel 110.

[0061] Understandably, the lower side of the reinforcing member 130 is connected to the first extension section 210, and the upper side of the reinforcing member 130 is connected to the inner plate of the rear wheel arch 110, so that the gap between the lower side of the reinforcing member 130 and the inner plate of the rear wheel arch 110 forms a cavity. The cavity has a buffering effect, which can block the road vibration transmitted by the wheel hub and reduce noise.

[0062] It should be noted that the first extension 210 and the second extension 220 of the rear floor 200, as well as the cross-section of the horizontal plane of the rear floor 200, form an "F" shape. The fastener 134 connecting the first extension 210 and the lower side of the reinforcing member 130 can be a bolt, screw, etc. At the same time, the overlapping structure 133 of the reinforcing member 130 overlaps with the first extension 210. The inner plate 110 of the rear wheel arch and the second extension 220 can be bonded by structural adhesive 125. Structural adhesive 125 is suitable for the connection between different materials such as aluminum alloy castings and steel castings, which can prevent galvanic corrosion and also has a lightweight effect.

[0063] As one possible implementation, there can be multiple connectors 120, which are spaced apart along the lower edge of the rear wheel arch inner plate 110. Multiple connectors 120 can enhance connection stability and structural strength. The width, length, shape, and surface curvature of the multiple connectors 120 can be different. The first connecting portion 123 and the second connecting portion 124 of different connectors 120 need to match the upper edge contour of the rear floor 200 and the lower edge contour of the rear wheel arch inner plate 110 at the location of the connector 120. Reinforcing members 130 can be installed at positions between different connectors 120.

[0064] Reference Figure 1 and Figure 2 As one possible implementation, the connector 120 includes a first connector 121 and a second connector 122, and the reinforcing member 130 includes a first reinforcing member 131 and a second reinforcing member 132; the first connector 121 is connected to the front side of the rear floor 200, and the second connector 122 is connected to the rear side of the rear floor 200; the first reinforcing member 131 is located between the first connector 121 and the second connector 122, and the second reinforcing member 132 is located at one end of the second connector 122 away from the first reinforcing member 131. The two connectors 120 and the two reinforcing members 130 extend along the side of the rear floor 200, and the sum of their lengths matches the side length of the rear floor 200 or the lower edge length of the rear wheel arch inner panel 110.

[0065] It is understandable that the aforementioned rear wheel arch assembly 100 and rear floor 200 are used in vehicles. The rear wheel arch assembly 100 is connected to the rear floor 200 through connectors 120 and reinforcing members 130. Different models can be adapted by using connectors 120 of different specifications and sizes, thereby reducing production costs.

[0066] This application provides a rear wheel arch assembly 100 for a vehicle. The rear wheel arch assembly 100 includes a rear wheel arch inner plate 110, a connector 120, and a reinforcing member 130. The rear wheel arch inner plate 110 is located on the side of the rear floor 200 of the vehicle. The connector 120 is connected to the rear wheel arch inner plate 110 and the rear floor 200. The reinforcing member 130 is connected to the side of the rear wheel arch inner plate 110 facing the rear floor 200, and its lower edge is connected to the rear floor 200. The lower edge of the reinforcing member 130 is provided with an overlapping structure 133, which abuts against the upper edge of the side of the rear floor 200. The rear wheel arch assembly 100 provided by this application can connect the rear wheel arch inner plate 110 and the aluminum alloy rear floor 200 of different vehicle models through different types of connectors 120. The aluminum alloy rear floor 200 does not require customization and design of different molds, thus reducing production costs.

[0067] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application.
