[0079] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0080] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments.

For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.
[0083] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described based on the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should be understood that when it is mentioned that an element is connected to another element "on" or "under", it can not only be directly connected to the other element "on" or "under", but also be indirectly connected to the other element "on" or "under" through an intermediate element.
[0084] The embodiment of the present application provides a vehicle body, such as Figures 1 to 5 As shown, the vehicle body includes a front beam 1 and a front panel 2. The front beam 1 includes a front beam body 11 and a front beam cover plate 12. The front beam cover plate 12 is provided with a first rib 121 and a second rib 122 extending along its length direction. Along the width direction of the front beam cover plate 12, a first connecting portion 123 is formed between the first rib 121 and the second rib 122. Along the width direction X of the vehicle body, both ends of the front panel 2 are respectively connected to a front beam 1. The front panel 2 includes a front panel body 21 and a second connecting portion 22 protruding toward the first connecting portion 123. The second connecting portion 22 is fixedly connected to the first connecting portion 123. Among them, along the width direction of the front beam covering plate 12, the front beam covering plate 12 is provided with a first connecting end 124 and a second connecting end 125, the first connecting end 124 is fixedly connected to the front panel body 21, so that the front beam body 11 and the first rib 121 form a first cavity 10, and the front beam body 11 is fixedly connected to the second connecting end 125 and the front panel body 21 respectively, so that the front beam body 11, the second rib 122 and the front panel body 21 form a second cavity 20.
[0085] The front panel 2 extends along the width direction X of the vehicle body, and a front beam 1 is connected to each end of the front panel 2. Figure 2 The schematic diagram of the connection structure between one of the front beams 1 and the front panel 2 is shown in FIG. Figure 2 Taking the structure in as an example, the connection structure between the front panel 2 and the other front beam 1 is the same.
[0086] Specifically, if Figure 3 As shown, the front beam cover plate 12 is provided with a first convex rib 121 and a second convex rib 122 that protrude in a direction away from the front panel 2. Along the width direction of the front beam cover plate 12, a concave rib is formed between the first convex rib 121 and the second convex rib 122, which is closer to the front panel 2 than the first convex rib 121 and the second convex rib 122. The concave rib is the first connecting portion 123. Figure 4 As shown, the dash panel 2 includes an integrally formed dash panel body 21 and a second connecting portion 22. Since the second connecting portion 22 protrudes toward the first connecting portion 123, the dash panel body 21 on both sides of the second connecting portion 22 forms a recessed portion further away from the front beam cover plate 12 relative to the second connecting portion 22. Figure 5 As shown, the first connecting end 124 and the first connecting portion 123 located on both sides of the first rib 121 are respectively welded to the front panel body 21 and the second connecting portion 22 on both sides of one of the recessed parts, so that a first cavity 10 is formed between the recessed part and the first rib 121; at the same time, the two sides of the front beam body 11 are respectively welded to the second connecting end 125 and the side of another recessed part away from the second connecting portion 22, so that a second cavity 20 is formed between the front beam body 11, the second rib 122 and the front panel body 21.
[0087] In this embodiment, by setting the first cavity 10 and the second cavity 20, sufficient deformation space can be provided for the front beam body 11, the front beam sealing plate 12 and the front panel 2. Even if the external force collision causes the front beam sealing plate 12 and the front panel 2 to be slightly deformed toward the first cavity 10 or the front beam body 11, the front beam sealing plate 12 and the front panel 2 to be slightly deformed toward the second cavity 20, it will not affect the structural strength of the connection between the front beam 1 and the front panel 2, thereby ensuring the collision performance of the connection structure between the two.
[0088] In the prior art, to ensure the structural strength of the connection between the front beam 1 and the front panel 2, a front panel reinforcement plate is usually installed on the front panel 2. The front panel reinforcement plate and the front beam cover plate 12 respectively enhance the structural strength of the front panel 2 and the front beam 1, thereby enhancing the structural strength of the connection between the two. However, this embodiment does not require a separate front panel reinforcement plate. Instead, the structural strength of the connection between the front beam 1 and the front panel 2 is ensured simply by providing a first connecting portion 123 and a second connecting portion 22 on the front beam cover plate 12 and the front panel 2, respectively. Compared to the prior art, this embodiment eliminates one component, solves the problem of redundant structure at the connection between the front beam 1 and the front panel 2, improves the integration of the vehicle body beam components, and reduces the number of components, making the manufacture and assembly of the vehicle body structure more convenient and facilitating the manufacturing precision of the vehicle body.
[0089] In addition, if Figure 2 As shown, the first rib 121 and the second rib 122 extend toward the door sill 3 and the A-pillar 8, which can transfer the collision force exerted on the front beam 1 to the door sill 3 and the A-pillar 8 along the extension direction of the first rib 121 and the second rib 122, thereby reducing the collision force acting on the front panel 2 and further improving the collision resistance of the front beam 1 and the front panel 2.
[0090] In a specific embodiment, Figure 3 As shown, along the longitudinal direction Y of the vehicle body, the front beam body 11 includes a first section 111 and a second section 112 that are fixedly connected. The second section 112 is used to be fixedly connected to the front beam cover plate 12 and the front panel body 21. Figure 6 As shown, the second section 112 includes an integrally formed parts integration portion 112a and an extension portion 112b. Along the length direction Y of the vehicle body, the two ends of the parts integration portion 112a are fixedly connected to the first section 111 and the door sill 3 respectively. Along the width direction X of the vehicle body, the extension portion 112b is fixedly connected to the parts integration portion 112a and the floor crossbeam (not shown in the figure).
[0091] like Figure 6 As shown, the parts integration portion 112a and the extension portion 112b extend along the length direction Y and the width direction X of the vehicle body respectively, so that the second section 112 is in a T-shaped structure as a whole, reducing the volume of the second section 112. The extension portion 112b is used to connect the floor beam. In this embodiment, the extension portion 112b and the parts integration portion 112a are set as an integrated structure, which is equivalent to integrating the floor beam into the second section 112, and as shown in FIG. Figure 6As shown, an integrally formed power battery mounting plate 112aa is provided on the parts integration portion 112a, which is equivalent to integrating the power battery mounting plate 112aa into the second section 112. Compared with the prior art, the power battery crossbeam structure is reduced, which can reduce the number of parts of the vehicle body and improve the manufacturing accuracy of the vehicle body. Moreover, the second section 112 is an integrated structure, which improves the connection strength between the parts integration portion 112a and the extension portion 112b compared to the split structure, and also improves the overall anti-collision ability of the second section 112.
[0092] In addition, the parts integration portion 112a can also be integrated with a skid mounting bracket (not shown in the figure) and other components, which can further improve the integration of body parts without affecting the installation of body parts.
[0093] In a specific embodiment, Figure 7 As shown, the threshold 3 includes a threshold inner panel 31 and a threshold rear panel 32 that are fixedly connected. The threshold inner panel 31 is fixedly connected to the second section 112 , and the threshold rear panel 32 includes an integrally formed rear panel body 321 and a rear beam connecting portion 322 .
[0094] In this embodiment, the rear beam connection portion 322 is integrated into the rear panel body 321, and there is no need to set up a separate rear beam connection piece, which can reduce one body part. Figure 7 As shown, a power battery mounting bracket 33 is formed on both the rocker inner panel 31 and the rocker rear panel 32. The power battery mounting bracket 33 is integrated with the rocker inner panel 31 and / or the rocker rear panel 32, improving battery installation stability and further reducing at least two body parts, thereby improving vehicle body manufacturing precision. Furthermore, when the parts are integrated into the rocker inner panel 31 and the rocker rear panel 32, compared to the prior art method of welding separate parts to the rocker inner panel 31 and the rocker rear panel 32, the number of welds is reduced, facilitating overall vehicle body assembly and improving vehicle body dimensional precision. Furthermore, because the parts are integrated into the rocker inner panel 31 and the rocker rear panel 32, the cross-sectional area of the rocker 3 is increased, thereby improving the vehicle body's bending stiffness.
[0095] In a specific embodiment, Figure 8 As shown, the vehicle body further includes a connecting pillar 30 extending along the height direction Z of the vehicle body. Along the length direction Y of the vehicle body, the end of the first section 111 away from the second section 112 is fixedly connected to the connecting pillar 30. Along the height direction Z of the vehicle body, the vehicle body further includes an upper bending beam 4, a front anti-collision beam 6, and a lower bending beam 5, which are arranged in sequence. The upper bending beam 4, the front anti-collision beam 6, and the lower bending beam 5 are all fixedly connected to the side of the connecting pillar 30 away from the first section 111.
[0096] As shown in the figure, along the length direction Y of the vehicle body, the two surfaces of the connecting column 30 are welded and fixed to the first section 111 and the front anti-collision beam 6 respectively, and along the height direction Z of the vehicle body, the two ends of the connecting column 30 are welded and fixed to the upper curved beam 4 and the lower curved beam 5 respectively, that is, the installation connection of the four parts of the front beam 1, the upper curved beam 4, the front anti-collision beam 6 and the lower curved beam 5 is realized by connecting the column 30. Compared with the prior art, an upper curved beam column is provided for connecting the upper curved beam 4 and the front anti-collision beam 6, an upper curved beam column connecting piece is provided for connecting the upper curved beam column and the front beam 1, an anti-collision beam connecting plate is provided for connecting the front beam 1 and the front anti-collision beam 6, and a lower curved beam connecting plate is provided for connecting the front anti-collision beam 6 and the lower curved beam 5. This embodiment can reduce 4 parts to 1 part, solving the problems of complex vehicle body manufacturing process and poor dimensional accuracy caused by the large number of parts in the prior art.
[0097] Specifically, the cross-section of the connecting column 30 is U-shaped. In this case, the structural rigidity and deformation resistance of the connecting column 30 can be improved, thereby improving the structural stability of the connecting column 30.
[0098] In a specific embodiment, Figure 9 As shown, the vehicle body also includes an electrical module mounting assembly 40, which includes two mounting cross beams 401 and two mounting longitudinal beams 402. Along the width direction X of the vehicle body, the two ends of the mounting cross beam 401 are fixedly connected to the two front beams 1 respectively, and along the length direction Y of the vehicle body, the two ends of the mounting longitudinal beam 402 are fixedly connected to the two mounting cross beams 401 respectively.
[0099] In this embodiment, the two mounting crossbeams 401 and the two mounting longitudinal beams 402 form a "well"-shaped structure for the electrical module mounting assembly 40. The mounting crossbeams 401 and the mounting longitudinal beams 402 are fixed by welding. The four ends of the "well"-shaped structure (the two ends of the two mounting crossbeams 401 along the vehicle body width direction X) are fixed to the two front beams 1 through fixing members 403, and the installation stability is good. The electrical module mounting assembly 40 is provided with a number of electrical component mounting points for installing MCUs of various specifications, fast and slow charging modules, and batteries. The mounting points of multiple electrical components are concentrated on the electrical module mounting assembly 40, which facilitates the assembly of electrical components. At the same time, the electrical components can be directly installed on the two mounting crossbeams 401 and the two mounting longitudinal beams 402, which can reduce the installation structure of some electrical components and help solve the problems in the prior art of the large number of mounting brackets for electrical components and the poor dimensional accuracy of the mounting points.
[0100] In this embodiment, the specific position of the electrical component installation point on the electrical module installation assembly 40 can be designed according to actual needs, and this embodiment does not impose any limitation on this.
[0101] In addition, a closed frame structure is formed between the front anti-collision beam 6, the two front beams 1 and a mounting crossbeam 401. At the same time, a closed frame structure is formed between another mounting crossbeam 401, the two front beams 1 and the front crossbeam 23 of the front panel, which can improve the torsional stiffness of the front end structure of the vehicle body and the front cabin mode.
[0102] Specifically, if Figure 10 As shown, avoidance holes 402a are provided at both ends of the mounting crossbeam 401. The avoidance holes 402a are connected to the outside world along the width direction X of the vehicle body. The electrical module mounting assembly 40 also includes a fixing part 403, which passes through the avoidance hole 402a and is fixedly connected to the front beam 1.
[0103] The avoidance hole 402a extends along the width direction X of the vehicle body and is connected to the outside. The rod portion of the fixing member 403 is used to pass through the avoidance hole 402a. Figure 10 As shown, along the longitudinal direction Y of the vehicle body, the size of the head of the fixing member 403 is larger than the size of the avoidance hole 402a. The edge of the head of the fixing member 403 can press the mounting crossbeam 401 to enable the mounting crossbeam 401 to be installed on the first section 111 of the front beam body 11. Specifically, the fixing member 403 can be a screw.
[0104] When the front end of the vehicle body is subjected to a head-on collision, the fixing part 403 becomes loose, and the area around the avoidance hole 402a is not limited by the fixing part 403, so that the avoidance hole 402a can move relative to the fixing part 403 along the width direction X of the vehicle body, that is, the mounting crossbeam 401 can be detached from the front beam 1, thereby ensuring that the front beam 1 can complete normal collapse when subjected to a collision, thereby improving the collision performance of the vehicle body.
[0105] In a specific embodiment, Figure 11 As shown, the vehicle body also includes a rear beam 7, which is fixedly connected to the rear beam connecting portion 322. A rear suspension arm mounting assembly 50 is provided on the rear beam 7. The rear suspension arm mounting assembly 50 includes an inner mounting plate 501 and an outer mounting plate 502. The inner mounting plate 501 includes a first side plate 501a and a second side plate 501b located on both sides of the first side plate 501a. The outer mounting plate 502 includes a third side plate 502a and a fourth side plate 502b located on both sides of the third side plate 502a. At least part of the second side plate 501b and at least part of the fourth side plate 502b are fixedly connected so that the inner mounting plate 501, the outer mounting plate 502 and the bottom surface of the rear beam 7 form a accommodating cavity 60.
[0106] In this embodiment, the rear beam 7 is connected to the front beam 1 through the door sill 3. A rear suspension arm mounting assembly 50 is welded and fixed to the rear beam 7 for mounting the front suspension arm of the rear suspension torsion beam (not shown in the figure). Figure 12As shown, at least portions of the two second side panels 501b and at least portions of the two fourth side panels 502b are welded and fixed to achieve a fixed connection between the inner mounting panel 501 and the outer mounting panel 502. Furthermore, the second side panels 501b and / or the fourth side panels 502b further include extension panels 504, which can be welded and fixed to the bottom and side surfaces of the rear beam 7. The extension panels 504 can increase the connection area between the inner mounting panel 501 and the outer mounting panel 502 and the rear beam 7, thereby ensuring the installation stability of the rear suspension swingarm mounting assembly 50 and the rear beam 7. At this point, the inner mounting panel 501, the outer mounting panel 502, and the bottom surface of the rear beam 7 can enclose a receiving cavity 60, within which the front swingarm of the rear suspension torsion beam is mounted.
[0107] In this embodiment, the rear suspension arm mounting assembly 50 only includes two parts, namely the mounting inner plate 501 and the mounting outer plate 502. Compared with the technical solution in the prior art which includes 6 parts, the rear suspension arm mounting assembly 50 provided in this embodiment can solve the problem of a large number of structural parts and complex overlap matching. In addition, the prior art adopts welding between multiple parts, which is prone to the problem of cold welding. This embodiment reduces the number of parts and can reduce the risk of cold welding.
[0108] The vehicle body provided in this application has two door sills 3 and two rear beams 7. The two door sills 3 are arranged opposite to each other along the width direction X of the vehicle body, and the two rear beams 7 are arranged opposite to each other along the width direction X of the vehicle body.

[0109] like Figure 12 As shown, the outer surfaces of the first side plate 501a and the third side plate 502a are both provided with reinforcing ribs 503. The reinforcing ribs 503 protrude in a direction away from the accommodating cavity 60, thereby increasing the structural strength of the inner and outer mounting plates 501, 502, and improving the dynamic stiffness of the rear suspension arm mounting assembly 50.
[0110] It should be noted that this embodiment does not limit the specific structure and size of the reinforcing rib 503.
[0111] In summary, the vehicle body structure provided by this application can reduce the number of parts, improve the integration of parts, reduce the weight of the vehicle body, and reduce the cost of the vehicle body. If applied to electric vehicles, it can also help improve the range of electric vehicles. By improving the integration of parts, the problems of complex part overlap and low body dimensional accuracy in the prior art can be solved. Moreover, since parts are usually fixed by welding, reducing the number of parts can also solve the problem of poor welding and ensure the connection stability of the vehicle body parts. In addition, the vehicle body structure provided by this application can also improve the collision performance of the vehicle body, thereby increasing the rigidity of the vehicle body and ensuring the reliability of the vehicle body structure.
[0112] An embodiment of the present application also provides a vehicle, which includes the body described in any of the above embodiments. Since the body has the above-mentioned technical effects, the vehicle including the planning god should also have corresponding technical effects, which will not be repeated here.
