[0027] The present application provides a vehicle body. Figure 1-Figure 3 The vehicle body 10 has a length direction, a width direction, and a height direction. The length direction, the width direction, and the height direction are orthogonal to each other. For example, the length direction may be Figure 1 The X-axis direction in the width direction can be Figure 1 The Y-axis direction in the height direction can be Figure 1The vehicle body 10 may include a sill outer panel front section 11, a sill outer panel rear section 12, a side panel 13, a sill inner panel 14 and a wheel cover 15. The sill inner panel 14, the sill outer panel front section 11 and the sill outer panel rear section 12 are arranged at the rear door of the vehicle body 10. The sill inner panel 14 may include two sections connected to each other, front and rear. The sill inner panel 14, the sill outer panel front section 11 and the sill outer panel rear section 12 at the two rear doors may be arranged in a similar manner. The sill inner panel 14, the sill outer panel front section 11 and the sill outer panel rear section 12 at one of the rear doors of the vehicle body 10 are used as an example for explanation. The sill outer panel front section 11 is closer to the front side of the vehicle body 10 in the length direction than the sill outer panel rear section 12. That is, the sill outer panel front section 11 is arranged on the side of the vehicle body 10 close to the front of the vehicle, and the sill outer panel rear section 12 is arranged on the side of the vehicle body 10 close to the rear of the vehicle. The side outer panel 13 is arranged on the outer side of the front section 11 of the rocker outer panel and the rear section 12 of the rocker outer panel, and covers at least a part of the front section 11 of the rocker outer panel and the rear section 12 of the rocker outer panel. The rocker inner panel 14 is arranged on the inner side of the front section 11 of the rocker outer panel and the rear section 12 of the rocker outer panel, and the two ends of the front section 11 of the rocker outer panel and the rear section 12 of the rocker outer panel in the height direction are respectively connected to the two ends of the rocker inner panel 14 in the height direction. The front section 11 of the rocker outer panel and the rear section 12 of the rocker outer panel are enclosed with the rocker inner panel 14 to form an internal space, that is, the front section 11 of the rocker outer panel, the rear section 12 of the rocker outer panel and the rocker inner panel 14 are partially convex, which can increase the rigidity of the component outside the plane relative to the flat plate-shaped component. The rocker inner panel 14, the front section 11 of the rocker outer panel and the rear section 12 of the rocker outer panel have certain strength and rigidity, and can absorb energy in the event of a side collision, thereby improving the anti-collision performance of the vehicle. The side panel 13 can have a certain buffering and protective effect, and can also have a decorative effect, thereby improving the appearance of the vehicle. The wheel cover 15 is arranged at the rear side of the door sill rear section 12 in the length direction. The wheel cover 15 can prevent dirt, stones and other debris from splashing onto the wheel hub, avoid scratches, rust and other problems on the wheel hub surface, and thus protect the wheel hub from the influence of the external environment.

[0028] In the related art, the front section 11 of the rocker outer panel and the rear section 12 of the rocker outer panel are usually allocated to two different assemblies. For example, the rear section 12 of the rocker outer panel is connected to the wheel cover 15 to form an assembly, and the front section 11 of the rocker outer panel is connected to the side panel 13 to form another assembly. The structural adhesive is pre-coated at the joint between the rear section 12 of the rocker outer panel and the front section 11 of the rocker outer panel. When the two assemblies are assembled to the vehicle body 10, the joint between the front section 11 of the rocker outer panel and the rear section 12 of the rocker outer panel is connected by the structural adhesive. In the above scheme, 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 of the rocker outer panel and the rear section 12 of the rocker outer panel, there is no operating space to reinforce the joint. The connection between the front section 11 of the rocker outer panel and the rear section 12 of the rocker outer panel depends on the structural adhesive, resulting in insufficient connection strength.

[0029] See also Figure 4 In order to solve the above technical problems, the vehicle body 10 provided by the present application, the rocker outer panel rear section 12 includes a first connection portion 121, the projection of the first connection portion 121 in the width direction at least partially falls on the rocker outer panel front section 11, and the first connection portion 121 is provided with a connection reinforcement structure 18 connecting the rocker outer panel rear section 12 and the rocker outer panel front section 11. That is, the first connection portion 121 partially overlaps with the rocker outer panel front section 11 in the length direction, so that the rocker outer panel rear section 12 and the rocker outer panel front section 11 are overlapped and connected. The connection reinforcement structure 18 is used to enhance the connection strength between the rocker outer panel front section 11 and the rocker outer panel rear section 12. During the assembly process, the rocker outer panel front section 11, the rocker outer panel rear section 12 and the side outer panel 13 form a first assembly body, so that the connection reinforcement structure 18 can be provided on the first connection portion 121 before the side outer panel 13 covers the outer side of the first connection portion 121. The rocker outer panel front section 11 , the rocker outer panel rear section 12 and the side panel outer panel 13 are arranged in the same assembly body, so that the three are formed into an assembly body and then connected with other assemblies (such as wheel cover 15 ).

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

[0031] In addition to the connection reinforcement structure 18 directly connecting the front section 11 and the rear section 12 of the sill outer panel, there may also be a connection structure shared with other components. For example, the front section 11 and the rear section 12 of the sill outer panel may be provided with a connection structure shared by the three at the connection points with the sill inner panel 14 at both ends in the height direction, such as screws passing through the three components, or three-layer welding points.

[0032] In one embodiment, the connection reinforcement structure 18 includes screws or rivets. Since the outer side of the first connection portion 121 is not covered by the side panel 13 during the assembly process, there is an operating space for assembling the screws or rivets at the first connection portion 121, and the screws or rivets can enhance the connection strength between the front section 11 and the rear section 12 of the rocker outer panel, thereby improving the anti-collision performance of the vehicle.

[0033] In one embodiment, if Figure 5As shown, the connection reinforcement structure 18 includes a first welding point 181, and the first welding point 181 is arranged within the coverage of the side outer panel 13. Compared with screws or rivets, welding points occupy less space, which can facilitate the arrangement of other components inside the vehicle body 10. The first welding point 181 can be one or more, which is not specifically limited here. Generally speaking, the side outer panel 13 covers the middle and upper area in the height direction of the first connecting portion 121, and the first welding point 181 is arranged within the coverage of the side outer panel 13. On the one hand, there is a welding point between the middle and upper area in the height direction of the first connecting portion 121 and the front section 11 of the rocker outer panel, and the welding points are distributed more dispersedly in the height direction of the first connecting portion 121, avoiding the absence of welding points in a larger range, which is conducive to enhancing the connection strength between the front section 11 of the rocker outer panel and the rear section 12 of the rocker outer panel, thereby improving the anti-collision performance of the vehicle; on the other hand, the side outer panel 13 covers outside the first welding point 181, and the side outer panel 13 can cover the first welding point 181, which can prevent the welding point from being exposed and affecting the appearance of the vehicle body 10.

[0034] In one embodiment, if Figure 5 As shown, the connection reinforcement structure 18 also includes a second welding point 182, and the second welding point 182 is arranged outside the coverage of the side outer panel 13. The second welding point 182 can be one or more. As mentioned above, the side outer panel 13 covers the middle and upper area in the height direction of the first connecting portion 121, and the second welding point 182 is arranged outside the coverage of the side outer panel 13, so that there is a welding point between the lower area in the height direction of the first connecting portion 121 and the front section 11 of the rocker outer panel, which increases the number of welding points, which is conducive to enhancing the connection strength between the front section 11 of the rocker outer panel and the rear section 12 of the rocker outer panel, thereby improving the anti-collision performance of the vehicle.

[0035] See also Figure 5In one embodiment, the rocker outer panel rear section 12 includes a second connection portion 122, which is located at the rear side of the rocker outer panel rear section 12 in the length direction and at the lower part of the rocker outer panel rear section 12 in the height direction. That is, the second connection portion 122 is located at the lower rear of the rocker outer panel rear section 12. During the assembly process, the wheel cover 15 forms a second assembly body, and the wheel cover 15 is welded to the second connection portion 122. The wheel cover 15 and the rear section 12 of the rocker outer panel are allocated to two different assemblies, so that the rear section 12 of the rocker outer panel can be connected to the front section 11 of the rocker outer panel first, and then the wheel cover 15 can be connected to the rear section 12 of the rocker outer panel. Compared with the solution in which the rear section 12 of the rocker outer panel is connected to the wheel cover 15 to form one assembly, and the front section 11 of the rocker outer panel is connected to the side outer panel 13 to form another assembly, since the outer side of the rear section 12 of the rocker outer panel is not covered by the side outer panel 13 when the rear section 12 of the rocker outer panel is connected to the front section 11 of the rocker outer panel, there is an operating space for setting the connection reinforcement structure 18 at the first connection portion 121, and the connection reinforcement structure 18 can enhance the connection strength between the front section 11 of the rocker outer panel and the rear section 12 of the rocker outer panel, thereby improving the anti-collision performance of the vehicle. In addition, the second connecting portion 122 connected to the wheel cover 15 is arranged at the lower rear of the rear section 12 of the rocker outer panel, so that the connecting position of the wheel cover 15 and the rear section 12 of the rocker outer panel can avoid the upper and middle area of ​​the rear section 12 of the rocker outer panel covered by the side outer panel 13, thereby preventing the side outer panel 13 from blocking the connecting position of the wheel cover 15 and the rear section 12 of the rocker outer panel, and facilitating the connection operation between the two.

[0036] In addition to directly welding the rocker panel rear section 12 and the wheel cover 15 at the second connection portion 122, there may also be a connection structure shared with other components. For example, three layers of welding points are provided between the rocker panel rear section 12, the wheel cover 15 and the side panel 13.

[0037] In one embodiment, if Figure 1 , Figure 5 , Figure 6As shown, the rear section 12 of the rocker outer panel includes a support portion 123, and the support portion 123 is connected between the first connection portion 121 and the second connection portion 122. A part of the support portion 123 protrudes toward the side where the side panel 13 is located, so that the stiffness of the rear section 12 of the rocker outer panel outside the plane can be increased. The vehicle body 10 includes an anti-collision beam 17 arranged at the rear door, and one end of the support portion 123 close to the second connection portion 122 extends toward the upper part of the vehicle body 10 in the height direction, so that the projection of one end of the anti-collision beam 17 close to 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. In this way, the lower end of the anti-collision beam 17 and the rear section 12 of the rocker outer panel have a large overlapping area in the height direction. During the side collision process, the support portion 123 forms a support for one end of the anti-collision beam 17, and the rear section 12 of the rocker outer panel can provide good support for the anti-collision beam 17, thereby reducing the intrusion amount and intrusion speed of the rear door, and improving the anti-collision performance of the vehicle.

[0038] See also Figure 2 , Figure 3 , Figure 7 In one embodiment, the vehicle body 10 includes a reinforcing plate 16. The reinforcing plate 16 can reinforce the door sill so that a clamp can be clamped at the door sill during vehicle assembly, or a jack can act on the door sill during vehicle maintenance. A portion of the reinforcing plate 16 is accommodated in a space enclosed by the rear section 12 of the door sill outer panel and the door sill inner panel 14, and both ends of the reinforcing plate 16 in the height direction are respectively connected to the two ends of the door sill inner panel 14 in the height direction. In this way, the reinforcing plate 16 extends in the height direction to the upper and lower stops of the door sill inner panel 14, and both upper and lower ends of the door sill inner panel 14 are connected to the reinforcing plate 16, so that the connection between the reinforcing plate 16 and the door sill inner panel 14 is more secure, and the door sill inner panel 14 can provide good support for the reinforcing plate 16, thereby improving the strength of the door sill.

[0039] In one embodiment, if Figure 3 , Figure 7 As shown, a local area of ​​the reinforcing plate 16 protrudes toward the side where the rear section 12 of the rocker outer panel is located to form a supporting protrusion 161, and the supporting protrusion 161 is welded to the rear section 12 of the rocker outer panel. The supporting protrusion 161 is arranged on the reinforcing plate 16 and is welded to the rear section 12 of the rocker outer panel, so that the reinforcing plate 16 can provide support for the rear section 12 of the rocker outer panel in the width direction, thereby improving the rigidity and strength of the rear section 12 of the rocker outer panel in the width direction, which is beneficial to improving the anti-collision performance of the vehicle.

[0040] See also Figure 4In one embodiment, a first avoidance groove 124 is provided at the upper portion of the rear section 12 of the rocker outer panel in the height direction, and the reinforcing plate 16 is welded to the rocker inner panel 14 through the first avoidance groove 124. By providing the avoidance groove on the rear section 12 of the rocker outer panel, the number of layers of welded components at the connection between the reinforcing plate 16 and the rocker inner panel 14 is reduced, the difficulty of welding between the reinforcing plate 16 and the rocker inner panel 14 is reduced, the welding quality can be ensured, and the connection between the reinforcing plate 16 and the rocker inner panel 14 is more reliable.

[0041] The first avoidance groove 124 can be one. For example, a first avoidance groove 124 is opened in the middle area of ​​the upper end of the rear section 12 of the sill outer plate, and the welding points between the upper end of the rear section 12 of the sill outer plate and the sill inner plate 14 are distributed on both sides of the first avoidance groove 124. Or, in one embodiment, as Figure 5 , Figure 7 As shown, there are two first avoidance grooves 124, and a second avoidance groove 162 is provided at the upper part of the reinforcing plate 16 in the height direction, and the portion of the rear section 12 of the rocker sill outer panel located between the two first avoidance grooves 124 can be welded to the rocker sill inner panel 14 through the second avoidance groove 162. In this configuration, in addition to the welding points being provided on both sides in the length direction between the upper end of the rear section 12 of the rocker sill outer panel and the rocker sill inner panel 14, the middle area of ​​the upper end of the rear section 12 of the rocker sill outer panel can also be welded to the rocker sill inner panel 14 through the second avoidance groove 162, which can reduce the spacing of the welding points in the length direction, thereby making the connection between the rear section 12 of the rocker sill outer panel and the rocker sill inner panel 14 more reliable.

[0042] The present application provides a vehicle. Figure 8 The vehicle 100 may include a vehicle body 10 and a wheel 20. The wheel 20 is mounted at the lower portion of the vehicle body 10, and is used to support the vehicle body 10. The wheel 20 may move under the drive of the engine and drive the vehicle body 10 to move. The vehicle 100 may be a vehicle driven by a fuel engine or a vehicle driven by an electric motor. Other structures of the vehicle 100 will not be described in detail.
