Description

Technical Field

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

[0002] With the increasing prevalence of vehicles, people have higher and higher requirements for vehicle collision safety. The joint between the front and rear sections of the rear door sill is a relatively weak point in the vehicle body structure, but this joint has a significant impact on the performance in small offset collisions, side collisions, or pole impacts. In related technologies, the joint between the front and rear sections of the sill is bonded with structural adhesive, resulting in insufficient connection strength and a risk of tearing in a collision. The connection between the front and rear sections of the sill affects the vehicle's crashworthiness. Summary of the Invention

[0003] This application provides a vehicle body and a vehicle that can solve the technical problem that the connection between the front section and the rear section of the sill outer panel affects the vehicle's collision protection performance.

[0004] To address the aforementioned technical problems, this application provides a vehicle body having a length direction and a width direction. The vehicle body includes a front section of the sill outer panel, a rear section of the sill outer panel, and a side panel. The front section of the sill outer panel is closer to the front side of the vehicle body in the length direction than the rear section of the sill outer panel. The side panel is disposed outside the front and rear sections of the sill outer panel and covers at least a portion of the front and rear sections of the sill outer panel. The rear section of the sill outer panel includes a first connecting portion. The projection of the first connecting portion in the width direction at least partially falls on the front section of the sill outer panel. The first connecting portion is provided with a connecting reinforcement structure connecting the rear and front sections of the sill outer panel. During assembly, the front and rear sections of the sill outer panel and the side panel form a first assembly, so that the connecting reinforcement structure can be provided at the first connecting portion before the side panel covers the outside of the first connecting portion.

[0005] In one embodiment, the connecting reinforcement structure includes a first weld point disposed within the coverage area of ​​the side panel.

[0006] In one embodiment, the connecting reinforcement structure further includes a second weld point located outside the coverage area of ​​the side panel.

[0008] In one embodiment, the vehicle body has a height direction and a width direction. The rear section of the sill outer panel includes a second connecting portion and a supporting portion. The second connecting portion is located on the rear side of the rear section of the sill outer panel in the length direction and at the lower part of the rear section of the sill outer panel in the height direction. The supporting portion is connected between the first connecting portion and the second connecting portion. A portion of the supporting portion protrudes towards the side where the side panel is located. The vehicle body includes a crash beam disposed at the rear door. The end of the supporting portion near the second connecting portion extends towards the upper part of the vehicle body in the height direction, so that the projection of the end of the crash beam near the lower part of the vehicle body in the height direction along the width direction falls within the range of the supporting portion.

[0009] In one embodiment, the vehicle body has a height direction, and the vehicle body includes a reinforcing plate and an inner sill plate. The inner sill plate is disposed inside the front section and the rear section of the outer sill plate. The two ends of the front section and the rear section of the outer sill plate in the height direction are respectively connected to the two ends of the inner sill plate in the height direction. A portion of the reinforcing plate is accommodated in the space formed by the rear section of the outer sill plate and the inner sill plate. The two ends of the reinforcing plate in the height direction are respectively connected to the two ends of the inner sill plate in the height direction.

[0010] In one embodiment, a local area of ​​the reinforcing plate protrudes towards the side where the rear section of the outer sill plate is located to form a support protrusion, and the support protrusion is welded to the rear section of the outer sill plate.

[0011] In one embodiment, a first clearance groove is provided at the upper part of the rear section of the outer sill plate in the height direction, and the reinforcing plate is welded to the inner sill plate through the first clearance groove.

[0012] In one embodiment, there are two first clearance grooves, and a second clearance groove is provided on the upper part of the reinforcing plate in the height direction. The part of the rear section of the outer sill plate located between the two first clearance grooves can be welded to the inner sill plate through the second clearance groove.

[0013] This application also provides a vehicle, which includes the body described above.

[0014] The vehicle body provided in this application forms a first assembly by setting a front section of the sill outer panel, a rear section of the sill outer panel, and a side panel. During the assembly process, the front section of the sill outer panel and the rear section of the sill outer panel can be connected first. At this time, the outer side of the first connection part is not covered by the side panel. The first connection part has an operating space for setting a connection reinforcement structure. The connection reinforcement structure can enhance the connection strength between the front section of the sill outer panel and the rear section of the sill outer panel, thereby improving the vehicle's anti-collision performance.

[0027] This application provides a vehicle body. Please refer to [link / reference]. Figures 1-3 The vehicle body 10 has a length direction, a width direction, and a height direction. The length direction, width direction, and height direction are orthogonal to each other. For example, the length direction can be... Figure 1 The X-axis direction and the width direction can be... Figure 1 The Y-axis direction and the height direction can be... Figure 1The Z-axis direction is shown in the diagram. The vehicle body 10 may include a front section 11 of the outer sill plate, a rear section 12 of the outer sill plate, a side panel 13, an inner sill plate 14, and wheel arches 15. The inner sill plate 14, the front section 11 of the outer sill plate, and the rear section 12 of the outer sill plate are located at the rear door of the vehicle body 10. The inner sill plate 14 may include two interconnected sections, front and rear. The arrangement of the inner sill plate 14, the front section 11 of the outer sill plate, and the rear section 12 of the outer sill plate at the two rear doors can be similar. The following explanation uses the inner sill plate 14, the front section 11 of the outer sill plate, and the rear section 12 of the outer sill plate at one of the rear doors of the vehicle body 10 as an example. The front section 11 of the outer sill plate is closer to the front of the vehicle body 10 in the length direction than the rear section 12 of the outer sill plate. That is, the front section 11 of the outer sill plate is located on the side of the vehicle body 10 closer to the front, and the rear section 12 of the outer sill plate is located on the side of the vehicle body 10 closer to the rear. The side panel 13 is disposed on the outer side of the front section 11 and the rear section 12 of the sill panel, and covers at least a portion of the front section 11 and the rear section 12. The inner sill panel 14 is disposed on the inner side of the front section 11 and the rear section 12 of the sill panel, with the two ends of the front section 11 and the rear section 12 of the sill panel respectively connected to the two ends of the inner sill panel 14 in the height direction. The front section 11 and the rear section 12 of the sill panel, together with the inner sill panel 14, form an internal space, meaning that the front section 11, the rear section 12, and the inner sill panel 14 are partially convex, which increases the out-of-plane stiffness of the component compared to a flat component. The inner sill panel 14, the front section 11, and the rear section 12 of the sill panel have a certain strength and stiffness, which can absorb energy during a side impact, thereby improving the vehicle's anti-collision performance. The side panel 13 provides both cushioning and protection, as well as decoration, enhancing the vehicle's aesthetics. Wheel covers 15 are located on the rear side of the rear section 12 of the door sill. Wheel covers 15 prevent dirt, stones, and other debris from splashing onto the wheel hub, avoiding scratches and rust on the hub surface, thus protecting the hub from environmental impacts.

[0028] In related technologies, the front section 11 and rear section 12 of the sill outer panel are typically assigned to two different assemblies. For example, the rear section 12 of the sill outer panel is connected to the wheel arch 15 to form one assembly, and the front section 11 of the sill outer panel is connected to the side panel 13 to form another assembly. Structural adhesive is pre-applied at the connection between the rear section 12 and the front section 11 of the sill outer panel. When the two assemblies are assembled to the vehicle body 10, the joint between the front section 11 and the rear section 12 of the sill outer panel is connected by structural adhesive. In the above solution, when the two assemblies are assembled to the vehicle body 10, since the side panel 13 covers the outside of the joint between the front section 11 and the rear section 12 of the sill outer panel, there is no operating space to reinforce the joint. The connection at the joint between the front section 11 and the rear section 12 of the sill outer panel relies on structural adhesive, resulting in insufficient connection strength.

[0029] Please see Figure 4 To solve the aforementioned technical problems, the vehicle body 10 provided in this application includes a first connecting portion 121 in the rear section 12 of the sill outer panel. The projection of the first connecting portion 121 along the width direction at least partially falls on the front section 11 of the sill outer panel. The first connecting portion 121 is provided with a connecting reinforcement structure 18 connecting the rear section 12 of the sill outer panel and the front section 11 of the sill outer panel. That is, the first connecting portion 121 and the front section 11 of the sill outer panel partially overlap in the length direction to facilitate the overlapping connection between the rear section 12 of the sill outer panel and the front section 11 of the sill outer panel. The connecting reinforcement structure 18 is used to enhance the connection strength between the front section 11 of the sill outer panel and the rear section 12 of the sill outer panel. During the assembly process, the front section 11 of the sill outer panel, the rear section 12 of the sill outer panel, and the side panel 13 form a first assembly. The connecting reinforcement structure 18 can be provided in the first connecting portion 121 before the side panel 13 covers the outside of the first connecting portion 121. The front section 11 of the sill outer panel, the rear section 12 of the sill outer panel, and the side panel 13 are arranged in the same assembly, so that the three are connected to other assemblies (such as wheel covers 15) after forming an assembly.

[0030] The vehicle body 10 provided in this application forms a first assembly by setting a front section 11 of the outer sill plate, a rear section 12 of the outer sill plate, and a side panel 13. During the assembly process, the front section 11 of the outer sill plate and the rear section 12 of the outer sill plate can be connected first. At this time, the outer side of the first connecting part 121 is not covered by the side panel 13. The first connecting part 121 has an operating space for setting a connecting reinforcement structure 18. The connecting reinforcement structure 18 can enhance the connection strength between the front section 11 of the outer sill plate and the rear section 12 of the outer sill plate, thereby improving the vehicle's anti-collision performance.

[0031] In addition to the connecting reinforcement structure 18 that directly connects the front section 11 and the rear section 12 of the outer sill plate, there can also be a connection structure shared with other components. For example, the front section 11 and the rear section 12 of the outer sill plate can have a shared connection structure at their two ends in the height direction where they connect with the inner sill plate 14, such as screws passing through the three components, or three layers of weld points.

[0032] In one embodiment, the connecting reinforcement structure 18 includes screws or rivets. Since the outer side panel 13 does not cover the outer side of the first connecting portion 121 during assembly, the first connecting portion 121 has operating space for mounting screws or rivets. The screws or rivets can enhance the connection strength between the front section 11 and the rear section 12 of the sill panel, thereby improving the vehicle's collision protection performance.

[0033] In one embodiment, such as Figure 5As shown, the connecting reinforcement structure 18 includes a first weld point 181, which is located within the coverage area of ​​the side outer panel 13. Compared to screws or rivets, weld points occupy less space, facilitating the arrangement of other components inside the vehicle body 10. There can be one or more first weld points 181; no specific limitation is made here. Generally, the side outer panel 13 covers the upper-middle region in the height direction of the first connecting portion 121. The first weld point 181 is located within the coverage area of ​​the side outer panel 13. On one hand, this ensures a welding point between the upper-middle region in the height direction of the first connecting portion 121 and the front section 11 of the sill outer panel. The welding points are relatively dispersed in the height direction of the first connecting portion 121, avoiding a large area without welding points. This enhances the connection strength between the front section 11 and the rear section 12 of the sill outer panel, thereby improving the vehicle's anti-collision performance. On the other hand, the side outer panel 13 covers the first weld point 181, preventing it from being exposed and affecting the appearance of the vehicle body 10.

[0034] In one embodiment, such as Figure 5 As shown, the connecting reinforcement structure 18 also includes a second weld point 182, which is located outside the coverage area of ​​the side outer panel 13. There can be one or more second weld points 182. As previously mentioned, the side outer panel 13 covers the upper-middle region in the height direction of the first connecting portion 121. The second weld point 182 is located outside the coverage area of ​​the side outer panel 13, creating a welding point between the lower region in the height direction of the first connecting portion 121 and the front section 11 of the sill outer panel. This increases the number of welding points, which helps to enhance the connection strength between the front section 11 and the rear section 12 of the sill outer panel, thereby improving the vehicle's collision protection performance.

[0035] Please see Figure 5In one embodiment, the rear section 12 of the sill outer panel includes a second connecting portion 122, which is located on the rear side of the rear section 12 in the length direction and at the lower part of the rear section 12 in the height direction. That is, the second connecting portion 122 is located at the lower rear of the rear section 12. During assembly, the wheel cover 15 forms a second assembly, and the wheel cover 15 is welded to the second connecting portion 122. By assigning the wheel arch 15 and the rear section 12 of the outer sill plate to two different assemblies, the rear section 12 of the outer sill plate can be connected to the front section 11 of the outer sill plate first, and then the wheel arch 15 can be connected to the rear section 12 of the outer sill plate. Compared with the scheme where the rear section 12 of the outer sill plate and the wheel arch 15 are connected to form one assembly, and the front section 11 of the outer sill plate and the side panel 13 are connected to form another assembly, since the outer side of the rear section 12 of the outer sill plate and the front section 11 of the outer sill plate are not covered by the side panel 13 when they are connected, the first connection part 121 has operating space for setting the connection reinforcement structure 18. The connection reinforcement structure 18 can enhance the connection strength between the front section 11 of the outer sill plate and the rear section 12 of the outer sill plate, thereby improving the vehicle's anti-collision performance. Furthermore, the second connecting part 122 of the wheel cover 15 is located at the lower rear of the sill outer panel rear section 12, so that the connection position between the wheel cover 15 and the sill outer panel rear section 12 can avoid the upper middle area of ​​the sill outer panel rear section 12 covered by the side panel outer panel 13, thereby preventing the side panel outer panel 13 from blocking the connection position between the wheel cover 15 and the sill outer panel rear section 12, which facilitates the connection operation between the two.

[0036] In addition to being directly welded together at the second connection part 122, the rear section 12 of the sill plate and the wheel arch 15 can also have a connection structure shared with other components. For example, the rear section 12 of the sill plate, the wheel arch 15, and the side panel 13 are provided with three layers of weld points.

[0037] In one embodiment, such as Figure 1 , Figure 5 , Figure 6As shown, the rear section 12 of the sill outer panel includes a support portion 123, which connects the first connecting portion 121 and the second connecting portion 122. A portion of the support portion 123 protrudes towards the side where the side panel 13 is located, thereby increasing the out-of-plane rigidity of the rear section 12 of the sill outer panel. The vehicle body 10 includes a crash beam 17 disposed at the rear door. The end of the support portion 123 near the second connecting portion 122 extends upward in the height direction toward the upper part of the vehicle body 10, so that the projection of the end of the crash beam 17 near the lower part of the vehicle body 10 in the height direction along the width direction falls within the range of the support portion 123. This arrangement allows the lower end of the crash beam 17 and the rear section 12 of the sill outer panel to have a large overlap area in the height direction. During a side collision, the support portion 123 forms a support for one end of the crash beam 17, and the rear section 12 of the sill outer panel can provide good support for the crash beam 17, thereby reducing the intrusion amount and intrusion speed of the rear door and improving the vehicle's crashworthiness.

[0038] Please see Figure 2 , Figure 3 , Figure 7 In one embodiment, the vehicle body 10 includes a reinforcing plate 16. The reinforcing plate 16 strengthens the sill, allowing a clamp to be held at the sill during vehicle assembly or a jack to be applied to the sill during vehicle maintenance. A portion of the reinforcing plate 16 is housed within the space formed by the rear section 12 of the outer sill panel and the inner sill panel 14. Both ends of the reinforcing plate 16 in the height direction are connected to both ends of the inner sill panel 14 in the height direction. This arrangement extends the reinforcing plate 16 in the height direction to the upper and lower stops of the inner sill panel 14, with both ends of the inner sill panel 14 connected to the reinforcing plate 16. This makes the connection between the reinforcing plate 16 and the inner sill panel 14 more robust, providing good support for the reinforcing plate 16 and thus improving the strength of the sill.

[0039] In one embodiment, such as Figure 3 , Figure 7 As shown, a local area of ​​the reinforcing plate 16 protrudes towards the side where the rear section 12 of the outer sill plate is located, forming a support protrusion 161. The support protrusion 161 is welded to the rear section 12 of the outer sill plate. By providing the support protrusion 161 on the reinforcing plate 16 and welding it to the rear section 12 of the outer sill plate, the reinforcing plate 16 can provide support in the width direction for the rear section 12 of the outer sill plate, thereby improving the rigidity and strength of the rear section 12 of the outer sill plate in the width direction, which is beneficial to improving the vehicle's collision protection performance.

[0040] Please see Figure 4In one embodiment, a first clearance groove 124 is provided in the upper part of the rear section 12 of the outer sill plate in the height direction, and the reinforcing plate 16 is welded to the inner sill plate 14 through the first clearance groove 124. By providing a clearance groove in the rear section 12 of the outer sill plate, the number of welding components at the connection between the reinforcing plate 16 and the inner sill plate 14 is reduced, the welding difficulty between the reinforcing plate 16 and the inner sill plate 14 is reduced, the welding quality can be ensured, and the connection between the reinforcing plate 16 and the inner sill plate 14 is made more reliable.

[0041] There can be only one first clearance groove 124. For example, a first clearance groove 124 can be formed in the middle region of the upper end of the rear section 12 of the outer sill plate, in which case the welding points between the upper end of the rear section 12 of the outer sill plate and the inner sill plate 14 are distributed on both sides of the first clearance groove 124. Alternatively, in one embodiment, as shown... Figure 5 , Figure 7 As shown, there are two first clearance grooves 124, and the reinforcing plate 16 has a second clearance groove 162 at its upper part in the height direction. The portion of the rear section 12 of the outer sill plate located between the two first clearance grooves 124 can be welded to the inner sill plate 14 through the second clearance groove 162. With this configuration, in addition to the welding points on both sides in the length direction, the middle area of ​​the upper end of the rear section 12 of the outer sill plate can also be welded to the inner sill plate 14 through the second clearance groove 162. This reduces the spacing of the welding points in the length direction, thereby making the connection between the rear section 12 of the outer sill plate and the inner sill plate 14 more reliable.

[0042] This application provides a vehicle. Please refer to [link / reference]. Figure 8 The vehicle 100 may include a body 10 and wheels 20. The wheels 20 are mounted on the lower part of the body 10, and the wheels 20 support the body 10. The wheels 20 can move under the drive of an engine, thus moving the body 10. The vehicle 100 may be a vehicle driven by a fuel engine or a vehicle driven by an electric motor. Other structural details of the vehicle 100 will not be elaborated further.
