[0069] For a better understanding of the technical solutions of the present application, the embodiments of the present application are described in detail below with reference to the drawings.

[0070] In a specific embodiment, the present application is further described in detail below by specific embodiments and in conjunction with the drawings.

[0071] It should be clear that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0072] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "an" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0073] It should be understood that the term "and / or" used herein is only to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are a "or" relationship.

[0074] It should be noted that the "up", "down", "left", "right" and other directional words described in the embodiments of the present application are described from the angle shown in the drawings, and should not be understood as a limitation of the embodiments of the present application. In addition, in the context, it should also be understood that when referring to an element connected to another element "on" or "below", it can not only be directly connected to another element "on" or "below", but also indirectly connected to another element "on" or "below" through an intermediate element.

[0075] The embodiments of the present application provide a vehicle body 1, such as Figure 1 , Figure 2 ,Figure 4 and Figure 5 As shown, the vehicle body 1 includes a front wheel arch outer plate 111, a front wheel arch outer plate reinforcing plate 112, and a first reinforcing tube 113. The front wheel arch outer plate reinforcing plate 112 is welded to the front wheel arch outer plate 111 and forms a first cavity 11. The first reinforcing tube 113 is fixedly connected to both the front wheel arch outer plate 111 and the front wheel arch outer plate reinforcing plate 112, and the first reinforcing tube 113 is located inside the first cavity 11.

[0076] Therefore, a first reinforcing tube 113 is provided inside the first cavity 11 to improve the rigidity and torsional resistance of the first cavity 11, thereby improving the torsional resistance of the front wheel arch area of ​​the vehicle body 1, and further improving the rigidity, structural stability and crashworthiness of the vehicle body 1. Simultaneously, the length direction of the first reinforcing tube 113 is parallel to the length direction of the vehicle body 1. When the vehicle body 1 encounters a frontal collision, the first reinforcing tube 113 can bend downwards to absorb energy, allowing the collision energy to be transferred downwards to the lower area of ​​the vehicle body 1. This reduces the risk of deformation and bending of the reinforcing plate 131 on the A-pillar, achieving higher collision rating requirements for the vehicle body 1, which is beneficial for protecting the driver and passengers, thereby improving the safety performance of the vehicle body 1.

[0077] In addition, such as Figure 5 As shown, the vehicle body 1 also includes a second fixed bracket 138. The first reinforcing tube 113 is fixedly connected to the front wheel arch outer plate 111 by welding through two second fixed brackets 138, so as to improve the firmness of the first reinforcing tube 113 in the first cavity 11.

[0078] In one possible embodiment, such as Figure 3 As shown, by increasing the height H of the overlap between the front wheel arch outer plate reinforcement plate 112 and the side assembly 136, the strength and rigidity of the connection between the front wheel arch area and the side assembly 136 are improved, the force transmission path of frontal collision and oblique collision is increased, and at the same time, it is beneficial to improve the bending and torsional resistance of the vehicle body 1.

[0079] Specifically, traditional vehicle bodies typically connect the front wheel arch outer panel reinforcement plate 112 to the side panel assembly 136 using three sets of bolts, resulting in an overlapping edge such as... Figure 3 As shown by the dashed black curve, in this embodiment, the height H of the overlap between the front wheel arch outer panel reinforcement plate 112 and the side panel assembly 136 is increased by adding a set of bolts, i.e., as shown in the figure. Figure 3 As shown by the solid black curve.

[0080] In one possible embodiment, such as Figure 5 As shown, the first reinforcing pipe 113 includes a first pipe section 113a and a second pipe section 113b along the length of the vehicle body 1. The first pipe section 113a is located on the side closer to the front of the vehicle, and the second pipe section 113b is located on the side closer to the rear of the vehicle. The diameter of the first pipe section 113a is smaller than the diameter of the second pipe section 113b.

[0081] In this embodiment, the diameter of the first pipe segment 113a is smaller than the diameter of the second pipe segment 113b, so that the rigidity of the first pipe segment 113a is lower than the rigidity of the second pipe segment 113b. When the vehicle body 1 encounters a frontal collision, the first pipe segment 113a is more likely to bend downward, which is conducive to energy absorption of the first reinforcing pipe 113, improves the reliability of the collision energy being transmitted toward the lower side of the vehicle body 1, reduces the risk of the collision energy being transmitted backward to the whole vehicle, and further reduces the risk of deformation of the whole vehicle, thereby greatly improving the crashworthiness and safety performance of the vehicle body 1.

[0082] In this embodiment, the first pipe segment 113a and the second pipe segment 113b are integrally formed, which is conducive to improving the rigidity and structural stability of the first reinforcing pipe 113.

[0083] In a possible embodiment, as shown in Figure 2 and Figure 5 shown, the diameter of the first reinforcing pipe 113 gradually increases along the side close to the tail from the head.

[0084] In this embodiment, the diameter of the first reinforcing pipe 113 gradually increases, that is, the rigidity of the first reinforcing pipe 113 gradually increases from the head toward the tail, so as to reduce the risk of deformation of the end of the first reinforcing pipe 113 close to the driver, and further reduce the risk of deformation of the A-pillar reinforcing plate 131.

[0085] In a possible embodiment, as shown in Figure 4 shown, the contour of the front wheel house outer panel 111 is U-shaped, and the contour of the front wheel house outer panel reinforcing plate 112 is I-shaped, so that the welding ends of the front wheel house outer panel 111 and the front wheel house outer panel reinforcing plate 112 are on the same side of the front wheel house outer panel reinforcing plate 112.

[0086] In this embodiment, the front wheel house outer panel 111 and the front wheel house outer panel reinforcing plate 112 are welded through the first welding end 114 and the second welding end 115. Since the outer contour of the front wheel house outer panel 111 is U-shaped and the outer contour of the front wheel house outer panel reinforcing plate 112 is I-shaped, the first welding end 114 and the second welding end 115 can be located on the same side of the front wheel house outer panel reinforcing plate 112, thereby reducing the risk of structural weakness caused by the welding ends being located on different sides of the front wheel house outer panel reinforcing plate 112. Therefore, the welding ends of the front wheel house outer panel 111 and the front wheel house outer panel reinforcing plate 112 are located on the same side of the front wheel house outer panel reinforcing plate 112, which is conducive to improving the axial load-bearing performance of the first cavity 11, and further improving the rigidity and structural stability of the first cavity 11.

[0087] In a possible embodiment, as shown in Figures 6-13As shown, the vehicle body 1 further comprises an A-pillar upper reinforcement assembly 12, an A-pillar upper reinforcement plate 131 and an A-pillar upper trim plate 132, and the A-pillar upper reinforcement assembly 12 is located between the A-pillar upper reinforcement plate 131 and the A-pillar upper trim plate 132. The A-pillar upper reinforcement assembly 12 comprises a second reinforcement tube 121 and a first skeleton 122, and the second reinforcement tube 121 is fixedly connected with the first skeleton 122.

[0088] In this embodiment, the A-pillar upper reinforcement assembly 12 is used to replace the traditional A-pillar inner panel of the vehicle body, and the first skeleton 122 is used to provide a mounting point for interior trim parts and wire harnesses and other components of the vehicle body 1. The second reinforcement tube 121 is arranged between the A-pillar upper reinforcement plate 131 and the A-pillar upper trim plate 132, which is conducive to improving the stiffness and crashworthiness of the A-pillar upper joint area.

[0089] In this embodiment, the second reinforcement tube 121 can be fixedly connected with the first skeleton 122 by bolts. Figure 8

[0090] In one possible embodiment, as shown in the drawings, the vehicle body 1 further comprises a front side plate 15 and a first fixing bracket 16, one end of the A-pillar upper reinforcement assembly 12 is fixedly connected with the A-pillar upper reinforcement plate 131 through the first fixing bracket 16, and the other end is fixedly connected with the front side plate 15 by bolts. Figures 11-13 In this embodiment, one end of the A-pillar upper reinforcement assembly 12 is fixedly connected with the A-pillar upper reinforcement plate 131 through the first fixing bracket 16 and by bolts, so as to improve the firmness and stability of the connection between the A-pillar upper reinforcement assembly 12 and the A-pillar upper reinforcement plate 131. The other end of the A-pillar upper reinforcement assembly 12 is fixedly connected with the front side plate 15 by bolts, so as to improve the firmness and stability of the connection between the A-pillar upper reinforcement assembly 12 and the front side plate 15.

[0091] In addition, as shown in the drawings, the A-pillar upper reinforcement assembly 12 is arranged to extend to the front door upper hinge reinforcement plate 137 at one end of the front side plate 15, and the second reinforcement tube is fixedly connected with the front door upper hinge reinforcement plate 137 by carbon dioxide gas shielded welding. Meanwhile, the end of the second reinforcement tube 121 close to the front door upper hinge reinforcement plate 137 can be aligned with the end of the first reinforcement tube 113 away from the vehicle head, i.e., the second reinforcement tube 121 and the first reinforcement tube 113 can abut each other, or part of the structure of the second reinforcement tube 121 and the first reinforcement tube 113 can overlap, so as to improve the effectiveness of the collision force transmission, reduce the risk of deformation of the vehicle body 1 caused by the force transmission to other components, and further improve the crashworthiness of the vehicle body 1.

[0092] Figure 7 Figure 10

[0093] ​​​​Therefore, in this embodiment, the A-pillar upper reinforcing assembly 12 is connected to the front side panel 15 and the A-pillar upper reinforcing plate 131 in good continuity, so that the rigidity performance of this part of the structure is high, the force transmission path is smoother, and the risk of bending deformation of the A-pillar area of the vehicle body 1 in the event of a frontal or offset collision is prevented.

[0094] In addition, in this embodiment, since the A-pillar upper reinforcing assembly 12 replaces the traditional vehicle body A-pillar upper inner panel, and the first skeleton 122 has no lap joint relationship with the side outer panel 136a, the first skeleton 122 can be applied to other different vehicle bodies 1, and the first skeleton 122 can be set according to the interior installation needs of the vehicle body 1, thereby enabling the A-pillar upper reinforcing assembly 12 to also be applied to other different vehicle bodies 1, i.e., the A-pillar upper reinforcing assembly 12 is independent of the styling design of the vehicle body 1, thereby facilitating rapid iterative development of the vehicle body 1, shortening the development cycle, and reducing development costs.

[0095] In a possible embodiment, as shown in Figure 14 The vehicle body 1 further comprises a C-pillar upper reinforcing assembly 18, the C-pillar upper reinforcing assembly 18 is fixedly connected with the A-pillar upper reinforcing assembly 12, the C-pillar upper reinforcing assembly 18 comprises a third reinforcing pipe and a second skeleton, or the vehicle body 1 further comprises a C-pillar upper reinforcing assembly 18, one end of the B-pillar upper reinforcing assembly 17 is connected with the C-pillar upper reinforcing assembly 18, and the other end is connected with the A-pillar upper reinforcing assembly 12, the B-pillar upper reinforcing assembly 17 comprises a fourth reinforcing pipe and a third skeleton.

[0096] In this embodiment, the C-pillar upper reinforcing assembly 18 is used to replace the traditional vehicle body rear side window upper beam inner panel, thereby facilitating improvement of the rigidity and crashworthiness of the C-pillar upper joint area of the vehicle body 1. In an embodiment, the end of the A-pillar upper reinforcing assembly 12 away from the vehicle head extends to the B-pillar upper joint area and is fixedly connected with the C-pillar upper reinforcing assembly 18, i.e., the structure of the A-pillar upper reinforcing assembly 12 extending can be used to replace the traditional vehicle body A-pillar inner panel extension to improve the rigidity and crashworthiness of the B-pillar upper joint area of the vehicle body 1. In another embodiment, the B-pillar upper reinforcing assembly 17 is used to replace the A-pillar inner panel extension, i.e., the B-pillar upper reinforcing assembly 17 is connected between the A-pillar upper reinforcing assembly 12 and the C-pillar upper reinforcing assembly 18. Therefore, this embodiment can improve the rigidity of the vehicle body 1, thereby improving the NVH performance of the vehicle body 1 and improving the comfort of the passengers.

[0097] In addition, since the B-pillar upper reinforcing assembly 17 and the C-pillar upper reinforcing assembly 18 are similar in structure to the A-pillar upper reinforcing assembly 12, i.e., the B-pillar upper reinforcing assembly 17 and the C-pillar upper reinforcing assembly 18 can also be applied to other different vehicle bodies 1, further reducing development costs.

[0098] In a possible embodiment, as shown in Figures 15-17As shown, the vehicle body 1 further comprises a fifth reinforcing pipe 14, a roof 139, an upper D-pillar reinforcing plate 133 and a side window reinforcing plate 134, the fifth reinforcing pipe 14 comprises a first end 141, a second end 142 and a third end 143, the first end 141 is fixedly connected with the roof 139, the second end 142 is fixedly connected with the side window reinforcing plate 134, and the third end 143 is fixedly connected with the upper D-pillar reinforcing plate 133.

[0099] In this embodiment, the vehicle body 1 is provided with the fifth reinforcing pipe 14, which is beneficial to improve the rigidity and anti-deformation capability of the roof 139, the upper D-pillar reinforcing plate 133 and the side window reinforcing plate 134, and further improve the crashworthiness of the vehicle body 1. At the same time, the vehicle body 1 is provided with the fifth reinforcing pipe 14, which is beneficial to improve the reliability and stability of the connection between the roof 139, the upper D-pillar reinforcing plate 133 and the side window reinforcing plate 134, and further improve the rigidity and structural stability of the D-pillar upper joint area of the vehicle body 1, and reduce the risk of torsional deformation of the D-pillar upper joint area due to collision.

[0100] In addition, as shown in Figure 17 , the vehicle body 1 further comprises a third fixing bracket 192, and the first end 141, the second end 142 and the third end 143 of the fifth reinforcing pipe 14 are fixedly connected with the roof 139, the side window reinforcing plate 134 and the upper D-pillar reinforcing plate 133 through the third fixing bracket 192 corresponding thereto. Among them, the fifth reinforcing pipe 14 is fixedly connected with the three third fixing brackets 192 by adopting the connection mode of bolts or carbon dioxide gas shielded welding.

[0101] In a possible embodiment, as shown in Figure 15 , the outer contour of the fifth reinforcing pipe 14 is Y-shaped.

[0102] In this embodiment, the fifth reinforcing pipe 14 is Y-shaped and is an integral structure, so that the fifth reinforcing pipe 14 has good rigidity and anti-torsion performance, greatly improving the bending and torsion resistance of the vehicle body 1.

[0104] In the embodiment, the D-pillar upper reinforcing assembly 19 is used to replace the D-pillar upper inner panel, thereby improving the rigidity of the D-pillar upper joint area and reducing the risk of deformation caused by a collision. In addition, since the D-pillar upper reinforcing assembly 19 has a structure similar to that of the A-pillar upper reinforcing assembly 12, i.e., the fourth framework 191 of the D-pillar upper reinforcing assembly 19 is independent of the styling surface of the vehicle body 1, the D-pillar upper reinforcing assembly 19 can also be applied to vehicle bodies 1 of other different vehicle models, thereby realizing rapid iterative development, shortening the development cycle, and reducing the development cost.

[0105] In addition, in a possible embodiment, the D-pillar upper reinforcing assembly 19 can also be used to replace the roof rear cross beam inner panel and the D-pillar lower inner panel, thereby reducing the number of parts of the vehicle body 1, so that the D-pillar upper reinforcing assembly 19 can be further applied to vehicle bodies 1 of other different vehicle models.
