[0042] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0043] like Figure 1 As shown, in one embodiment, the side structure 10 is an integrally thermoformed structure. The side structure 10 includes an A-pillar structure 1, a B-pillar structure 2, and a C-pillar structure 3. The front side of the B-pillar structure 2 is connected to the A-pillar structure 1, and the B-pillar structure 2 and the A-pillar structure 1 together form a front door opening 101. The rear side of the B-pillar structure 2 is connected to the C-pillar structure 3, and the B-pillar structure 2 and the C-pillar structure 3 together form a rear door opening 102. The C-pillar structure 3 includes a first connecting part 31 and / or a second connecting part 32. When the C-pillar structure 3 includes the first connecting part 31, the first connecting part 31 is adapted to connect to the rear wheel arch inner panel support structure 20. When the C-pillar structure 3 includes the second connecting part 32, the second connecting part 32 is adapted to connect to the D-pillar structure 30.

[0044] In existing technologies, when the side panel structure is a one-piece thermoformed structure, its C-pillar structure typically does not have a first connecting part 31 and a second connecting part 32. In contrast, the arrangement in this embodiment increases the coverage area of ​​the side panel structure 10, allowing the main reinforcing components on the side of the vehicle body to be integrated into a single thermoformed part, thereby improving the overall rigidity, modal strength, and durability of the vehicle body. Simultaneously, this embodiment allows for a reduction in the material thickness of some structures within the side panel structure 10 while maintaining its strength, thus achieving weight and cost reduction. Furthermore, during subsequent assembly, the related functional component mounting structures, by connecting to the side panel structure 10, can achieve better local rigidity performance.

[0045] In addition, the arrangement in this embodiment can also ensure that the entire occupant is covered by the side enclosure structure 10 in a side collision, thereby providing better protection for the occupant.

[0046] In addition, the configuration in this embodiment improves the integration of the overall vehicle body structure, reduces the number of parts and welds, and can reduce the number of production stations.

[0047] "The side panel structure 10 is a one-piece hot-pressed molding structure" means that the A-pillar panel 4, B-pillar panel 5, and C-pillar panel 6 are first spliced ​​together to form the side panel. Figure 2 The side panel shown is the assembled side panel. Then, the side panel is subjected to thermoforming process to obtain side structure 10. Among them, A-column panel 4 becomes A-column structure 1 after thermoforming process, B-column panel 5 becomes B-column structure 2 after thermoforming process, and C-column panel 6 becomes C-column structure 3 after thermoforming process.

[0048] In one embodiment, the C-pillar structure 3 is a one-piece molded structure. This can further improve the strength of the side structure 10.

[0049] The phrase "C-pillar structure 3 is a one-piece molded structure" can mean that C-pillar structure 3 is a single, complete panel, rather than being composed of multiple panels pieced together. In other words, the aforementioned C-pillar panel 6 is a single, complete panel that undergoes a thermoforming process to become C-pillar structure 3.

[0050] like Figure 1 As shown, in one embodiment, the C-pillar structure 3 includes a first connecting portion 31 and a second connecting portion 32, with the second connecting portion 32 connected above the first connecting portion 31. This allows the side structure 10 to integrate more components.

[0051] The first connecting part 31 extends along the vertical direction of the vehicle, and the second connecting part 32 is connected to the upper end of the first connecting part 31.

[0052] like Figure 1 As shown, in one embodiment, the second connecting portion 32 is tilted forward along an upward direction. Specifically, the upper end of the second connecting portion 32 is located in front of the lower end of the second connecting portion 32.

[0053] exist Figure 1 In the example shown, the part of the C-pillar structure 3 located to the right of the dashed line a and below the dashed line b can be regarded as the area where the first connecting part 31 is located, and the part of the C-pillar structure 3 located between the dashed lines b and c can be regarded as the area where the second connecting part 32 is located.

[0054] Among them, dashed lines a, dashed lines b, and dashed lines c, d, e, and f mentioned below are all indicator lines drawn to facilitate understanding of the approximate location of the corresponding structures described in this article. These dashed lines are not present in the actual product.

[0055] like Figure 1 As shown, in one embodiment, the C-pillar structure 3 further includes a third connecting part 33, which is located in front of the first connecting part 31. The lower end of the third connecting part 33 is spliced ​​with the lower end of the B-pillar structure 2, and the upper end of the third connecting part 33 is connected to the front side of the lower end of the first connecting part 31. The first connecting part 31 protrudes upward from the upper end of the third connecting part 33.

[0056] The third connecting part 33 protrudes downward from the lower end of the first connecting part 31. Figure 1 In the example shown, the part of the C-pillar structure 3 located between the dashed lines a and d can be regarded as the area where the second connecting part 32 is located.

[0057] Furthermore, "the upper end of the third connecting part 33 is connected to the lower front side of the first connecting part 31" means that the upper end of the third connecting part 33 is connected to the lower end of the first connecting part 31, and the upper end of the third connecting part 33 is located in front of the lower end of the first connecting part 31. After assembly, the third connecting part 33 is located in front of the first connecting part 31.

[0058] Furthermore, the lower end of the third connecting part 33 can be welded to the lower end of the B-pillar structure 2, that is, the lower end of the third connecting part 33 is welded together with the lower end of the B-pillar structure 2. Meanwhile, the third connecting part 33 is located at the rear end of the B-pillar structure 2.

[0059] Furthermore, the third connecting portion 33 is inclined forward along the top-to-bottom direction. Specifically, the upper end of the third connecting portion 33 is located behind the lower end of the third connecting portion 33.

[0060] like Figure 1 As shown, in one embodiment, the C-pillar structure 3 further includes a C-pillar sill area 34, which connects to the third connecting portion 33 and is located at the lower end of the third connecting portion 33. The C-pillar sill area 34 extends along the longitudinal direction of the vehicle. Furthermore, the C-pillar sill area 34 protrudes forward from the third connecting portion 33, and its front end is joined to the lower end of the B-pillar structure 2. In this embodiment, the third connecting portion 33 connects to the B-pillar structure 2 via the C-pillar sill area 34, thereby achieving the joint with the B-pillar structure 2.

[0061] Among them, Figure 1 In the example shown, the portion of the C-pillar structure 3 located below the dashed line d can be considered as the area where the C-pillar threshold area 34 is located. Furthermore, the C-pillar threshold area 34 is used to form the outer threshold panel; after assembly, the C-pillar threshold area 34 is part of the outer threshold panel.

[0062] Additionally, the C-pillar sill area 34 and the B-pillar structure 2 can be connected together using a laser welding process. Figure 1 The line at W1 represents the weld between the two.

[0063] like Figure 1 As shown, in one embodiment, the C-pillar structure 3 further includes an upper C-pillar beam area 35, which extends along the front-rear direction of the vehicle; the rear end of the upper C-pillar beam area 35 is connected to the upper end of the second connecting part 32, and the front end of the upper C-pillar beam area 35 is spliced ​​with the upper end of the B-pillar structure 2.

[0064] Among them, Figure 1 In the example shown, the part of the C-column structure 3 located in front of the dashed line c can be regarded as the area where the upper beam area 35 of the C-column is located.

[0065] Furthermore, the front end of the upper beam section 35 of the C-column can be welded to the upper end of the B-column structure 2, meaning the front end of the upper beam section 35 of the C-column is welded together with the upper end of the B-column structure 2. Simultaneously, the upper beam section 35 of the C-column is located at the rear end of the B-column structure 2.

[0066] Furthermore, the upper beam area 35 and the B-column structure 2 can be connected together using a laser welding process, wherein, Figure 1 The line at W2 in the diagram represents the weld between the two.

[0067] In this embodiment, the upper end of the C-column structure 3 (i.e., the upper beam area 35 of the C-column) and the lower end of the C-column structure 3 (i.e., the threshold area 34 of the C-column) are both connected to the B-column structure 2 by splicing. During production, the C-column plate 6 is connected to the B-column plate 5 by splicing. This can avoid material waste. At the same time, the materials and thicknesses of the C-column plate 6 and the B-column plate 5 can be selected according to different rigidity requirements, which can reduce costs.

[0068] like Figure 1 As shown, the upper end of the third connecting portion 33 is spaced apart from the second connecting portion 32, and the space between them can be used to form a rear triangular window, for example, as shown in the reference. Figure 4 In subsequent use, the upper end of the third connecting part 33 is connected to a support plate 40, and the other end of the support plate 40 is connected to the rear end of the upper side beam area 35 of the C-pillar. Moreover, the support plate 40 is located in front of the third connecting part 33 and below the upper side beam area 35 of the C-pillar. After assembly, the first connecting part 31, the second connecting part 32, the third connecting part 33, the upper side beam area 35 of the C-pillar, and the support plate 40 together form the window of the rear triangular window, wherein the window of the rear triangular window extends through the C-pillar structure 3 along the left and right direction of the vehicle.

[0069] In addition, during subsequent assembly, a sealing strip can be installed on the support plate 40. This sealing strip can be used to fit the rear door and seal the rear door opening.

[0070] like Figure 1 As shown, in one embodiment, a front triangular window annular structure is provided at the upper end of the A-pillar structure 1. The front triangular window annular structure surrounds and forms a triangular hole 11, which penetrates the A-pillar structure 1 along the left-right direction of the vehicle. In subsequent production, glass can be installed at the front triangular window annular structure so that the driver can observe the external environment from here. It should be understood that the front triangular window annular structure surrounds and forms holes of other shapes.

[0071] like Figure 1As shown, in one embodiment, the A-pillar structure 1 includes a first A-pillar plate 12 and a second A-pillar plate 13. The upper end of the first A-pillar plate 12 is spliced ​​to the upper end of the B-pillar structure 2, and the lower end of the first A-pillar plate 12 is spliced ​​to the lower end of the B-pillar structure 2. The second A-pillar plate 13 is spliced ​​to the upper front side of the first A-pillar plate 12, and the first A-pillar plate 12 and the second A-pillar plate 13 together form a front triangular window ring structure. This arrangement can optimize the results of frontal collisions and small offset collisions, improving vehicle safety.

[0072] The phrase "the second A-pillar plate 13 is spliced ​​to the upper front side of the first A-pillar plate 12" can mean that the second A-pillar plate 13 is spliced ​​to the upper end of the first A-pillar plate 12, and the second A-pillar plate 13 is located in front of the first A-pillar plate 12.

[0073] Meanwhile, the splicing of the first A-column plate 12 and the second A-column plate 13 by the A-column structure 1 can not only reduce material waste, but also allow for the selection of materials and thicknesses of the C-column plate 6 and the B-column plate 5 according to different rigidity requirements, thereby reducing costs.

[0074] In addition, the first A-column plate 12 can be spliced ​​with the second A-column plate 13 by welding, that is, the first A-column plate 12 and the second A-column plate 13 are welded together.

[0075] Furthermore, the first A-pillar plate 12 and the second A-pillar plate 13 can be connected together by a laser welding process, wherein, Figure 1 The line at W3 represents the weld between the two.

[0076] In one embodiment, the strength of the second A-pillar plate 13 is less than that of the first A-pillar plate 12. Upon collision, the second A-pillar plate 13 is more prone to crumple deformation, thereby absorbing energy and improving vehicle safety.

[0077] In addition, "the strength of the second A-column plate 13 is less than the strength of the first A-column plate 12" mainly includes: the tensile strength of the second A-column plate 13 is less than the tensile strength of the first A-column plate 12, and the compressive strength of the second A-column plate 13 is less than the compressive strength of the first A-column plate 12.

[0078] like Figure 1 As shown, in one embodiment, the upper end of the first A-pillar plate 12 is provided with a first notch 121 opening towards the second A-pillar plate 13, and the rear end of the second A-pillar plate 13 is provided with a second notch 131 opening towards the first notch 121. The first notch 121 and the second notch 131 are connected to form a triangular hole 11, and a front triangular window annular structure surrounds the triangular hole 11. This arrangement is more conducive to the collapse and deformation of the second A-pillar plate 13, thereby improving its energy absorption effect.

[0079] like Figure 1As shown, in one embodiment, the first A-pillar plate 12 has an A-pillar sill area 122 extending in the front-rear direction of the vehicle, and the rear end of the A-pillar sill area 122 is spliced ​​with the lower end of the B-pillar structure 2.

[0080] The rear end of the A-pillar sill area 122 can be welded to the lower end of the B-pillar structure 2, meaning the rear end of the A-pillar sill area 122 is welded together with the lower end of the B-pillar structure 2. Simultaneously, the A-pillar sill area 122 is located in front of the B-pillar structure 2.

[0081] exist Figure 1 In the diagram, the portion of the first A-pillar plate 12 located below the dotted line e is the area where the A-pillar threshold area 122 is situated. Furthermore, the A-pillar threshold area 122 and the B-pillar structure 2 can be connected together using a laser welding process. Figure 1 The line at W4 represents the weld between the two.

[0082] like Figure 1 As shown, in one embodiment, the A-pillar sill area 122 includes a first sill 123 and a second sill 124 joined together, with the rear end of the second sill 124 joined to the lower end of the B-pillar structure 2. This allows for the selection of thickness and materials based on the actual strength requirements of different areas of the sill outer panel.

[0083] In one embodiment, the strength of the second threshold 124 is less than the strength of the first threshold 123, and the strength of the second threshold 124 is less than the strength of the B-pillar.

[0084] Additionally, the first threshold 123 and the second threshold 124 can be connected together using a laser welding process, wherein, Figure 1 The line at W5 represents the weld between the two.

[0085] like Figure 1 As shown, in one embodiment, the first A-pillar plate 12 further includes an A-pillar plate main area 125 and an A-pillar upper beam area 126; the A-pillar plate main area 125 is connected to the second A-pillar plate 13 to enclose and form a front triangular window ring structure; the front end of the A-pillar upper beam area 126 is connected to the upper end of the A-pillar plate main area 125, and the rear end of the A-pillar upper beam area 126 is spliced ​​with the upper end of the B-pillar structure 2; the front end of the first sill 123 is connected to the lower end of the A-pillar plate main area 125; the first sill 123, the A-pillar plate main area 125, and the A-pillar upper beam area 126 are integrally formed structures.

[0086] The portion of the first A-column slab 12 located between dashed lines e and f is the area of ​​the main section 125 of the A-column slab. The portion of the first A-column slab 12 located behind dashed line f is the area of ​​the upper beam section 126 of the A-column.

[0087] In this embodiment, the upper end of the A-column structure 1 (i.e., the upper beam area 126 of the A-column) and the lower end of the A-column structure 1 (i.e., the threshold area 122 of the A-column) are both connected to the B-column structure 2 by splicing. During production, the A-column plate 4 is connected to the B-column plate 5 by splicing. This can avoid material waste. At the same time, the materials and thicknesses of the A-column plate 4 and the B-column plate 5 can be selected according to different rigidity requirements to reduce costs.

[0088] In addition, the first threshold 123, the main area of ​​the A-pillar panel 125, and the upper beam area of ​​the A-pillar 126 are designed as a single molded structure, which can be formed into the corresponding structure through thermoforming. Designing these three as a single molded structure improves the integration of this area and balances processing costs (such as welding costs) and material costs.

[0089] In addition, the main area 125 of the A-pillar panel and the second A-pillar panel 13 are connected to form the outer A-pillar panel of the side structure 10.

[0090] In one embodiment, the upper beam area 126 of column A can be welded to column structure 2 of column B, that is, column upper beam area 126 of column A is welded together with column structure 2 of column B. At the same time, column upper beam area 126 of column A is located in front of column structure 2 of column B.

[0091] Additionally, the upper beam area 126 of column A and the structure 2 of column B can be connected together using a laser welding process. Figure 1 The line at W6 in the diagram represents the weld between the two.

[0092] like Figure 1 As shown, in one embodiment, the B-pillar structure 2 includes a B-pillar main board 21, a B-pillar upper beam area 22, and a B-pillar sill area 23. The upper end of the B-pillar main board 21 is connected to the middle part of the B-pillar upper beam area 22, and the lower end of the B-pillar main board 21 is connected to the middle part of the B-pillar sill area 23. The front end of the B-pillar upper beam area 22 is spliced ​​to the upper end of the A-pillar structure 1, and the rear end of the B-pillar upper beam area 22 is spliced ​​to the upper end of the C-pillar structure 3. The front end of the B-pillar sill area 23 is spliced ​​to the lower end of the A-pillar structure 1, and the rear end of the B-pillar sill area 23 is spliced ​​to the lower end of the C-pillar structure 3. In this embodiment, the B-pillar structure 2 is generally in the shape of an "I", which facilitates its connection to the A-pillar structure 1 and the C-pillar structure 3.

[0093] Furthermore, "the front end of the upper beam area 22 of column B is spliced ​​with the upper end of the structure 1 of column A" actually refers to the splicing of the front end of the upper beam area 22 of column B with the rear end of the upper beam area 126 of column A. The two can be welded together, and W6 is the weld between them.

[0094] "The rear end of the upper beam area 22 of column B is spliced ​​with the upper end of the structure 3 of column C" actually means that the rear end of the upper beam area 22 of column B is spliced ​​with the front end of the upper beam area 35 of column C. The two can be welded together, and W2 is the weld between them.

[0095] "The front end of the B-pillar sill area 23 is spliced ​​with the lower end of the A-pillar structure 1" actually means that the front end of the B-pillar sill area 23 is spliced ​​with the rear end of the A-pillar sill area 122. The two can be welded together, and W4 is the weld between them.

[0096] "The rear end of the B-pillar sill area 23 is spliced ​​with the lower end of the C-pillar structure 3" actually means that the rear end of the B-pillar sill area 23 is spliced ​​with the front end of the C-pillar sill area 34. The two can be welded together, and W1 is the weld between them.

[0097] Furthermore, after assembly, the upper beam area 126 of column A, the upper beam area 22 of column B, and the upper beam area 35 of column C are connected to form the outer plate of the upper beam of the side structure 10. The threshold area 122 of column A (including the first threshold 123 and the second threshold 124), the threshold area 23 of column B, and the threshold area 34 of column C are connected to form the outer plate of the threshold beam of the side structure 10.

[0098] like Figure 1 As shown, in one embodiment, the B-pillar main panel 21 includes a first B-pillar 211, a second B-pillar 212, and a third B-pillar 213. The upper end of the first B-pillar 211 is connected to the upper beam area 22 of the B-pillar, the lower end of the first B-pillar 211 is spliced ​​to the upper end of the second B-pillar 212, the lower end of the second B-pillar 212 is spliced ​​to the upper end of the third B-pillar 213, and the lower end of the third B-pillar 213 is connected to the B-pillar sill area 23. The first B-pillar 211 and the upper beam area 22 are integrally formed structures; the third B-pillar 213 and the sill area 23 are integrally formed structures. This allows for the selection of materials and thicknesses for the A-pillar plate 4 and the B-pillar plate 5 according to different rigidity requirements, thereby reducing costs.

[0099] Among them, the first section of B-pillar 211 and the upper beam area 22 of B-pillar are connected to form a "T"-shaped structure, and the third section of B-pillar 213 and the threshold area 23 of B-pillar are connected to form an inverted "T"-shaped structure.

[0100] Furthermore, the first B-pillar segment 211 can be welded to the second B-pillar segment 212, meaning the first B-pillar segment 211 and the second B-pillar segment 212 are welded together. Moreover, the first B-pillar segment 211 and the second B-pillar segment 212 can be connected using a laser welding process. Figure 1 The line at W7 represents the weld between the two.

[0101] Furthermore, the second B-pillar 212 can be joined to the third B-pillar 213 by welding, meaning the second B-pillar 212 and the third B-pillar 213 are welded together. Moreover, the second B-pillar 212 and the third B-pillar 213 can be connected using a laser welding process. Figure 1 The line at W8 in the diagram represents the weld between the two.

[0102] like Figure 2 As shown, in one embodiment, the A-column plate 4 includes a first plate 41, a second plate 42, and a third plate 43, with the second plate 42 splicing the first plate 41 and the third plate 43. After the A-column structure 1 is formed by a subsequent molding process, the first plate 41 forms the second A-column plate 13, the second plate 42 forms the first threshold section, the main area 125 of the A-column plate, and the upper beam area 126 of the A-column; and the third plate 43 forms the second threshold section 124.

[0103] B-column slab 5 includes a fourth slab 51, a fifth slab 52, and a sixth slab 53. The fifth slab 52 is spliced ​​with the fourth slab 51 and the sixth slab 53. After the B-column structure 2 is formed by the molding process, the fourth slab 51 forms the first section of B-column 211 and the upper beam area 22 of B-column, the fifth slab 52 forms the second section of B-column 212, and the sixth slab 53 forms the third section of B-column 213 and the threshold area 23 of B-column.

[0104] like Figure 2 and Figure 3 As shown, in one embodiment, the side structure 10 further includes a patch plate 7, which is spliced ​​onto any one or more of the A-pillar structure 1, B-pillar structure 2, and C-pillar structure 3. Here, "multiple" means two or more, and the meaning of the term "multiple" is the same in all embodiments and will not be repeated hereafter.

[0105] Among them, patch plate 7 is used to improve the rigidity of side structure 10, and it can be set according to actual needs. For example, in Figure 2 and Figure 3 In the example shown, patch plate 7 is provided with threaded rods for a first patch plate 71, a second patch plate 72, a third patch plate 73, and a fourth patch plate 74. A portion of the first patch plate 71 is located in the upper beam area 126 of the A-pillar of the A-pillar structure 1, and another portion of the first patch plate 71 is located in the upper beam area 22 of the B-pillar of the B-pillar structure 2. A portion of the second patch plate 72 is located in the sill area 122 of the A-pillar of the A-pillar structure 1, and another portion of the second patch plate 72 is located in the sill area 23 of the B-pillar of the B-pillar structure 2. The third patch plate 73 is located in the second section of the B-pillar 212 of the B-pillar structure 2, and the fourth patch plate 74 is located in the third connecting part 33 of the C-pillar structure 3.

[0106] In addition, each patch 7 is located inside the side structure 10, where "inside the side structure 10" refers to the side of the side structure 10 that is close to the passenger compartment after it is applied to the vehicle.

[0107] Furthermore, during production, the A-pillar plate 4, B-pillar plate 5, C-pillar plate 6, and each patch plate 7 can be spliced ​​(actually welded) together and then processed through a heat treatment process to obtain the final required side panel structure 10. In addition, the triangular hole 11 of the annular structure of the front triangular window can be processed during the heat treatment process.

[0108] like Figure 4 As shown, this utility model embodiment also provides a vehicle body, which includes the side structure 10 described in any of the above embodiments.

[0109] like Figure 4 As shown, in one embodiment, the vehicle body further includes a rear wheel arch inner panel support structure 20, which is connected to the first connecting portion 31. After assembly, the rear wheel arch inner panel support structure 20 is located inside the side panel structure 10.

[0110] like Figure 4 As shown, in one embodiment, the vehicle body also includes a D-pillar 30, a rear wheel arch connected to a first connecting portion 31, and a D-pillar 30 connected to a second connecting portion 32.

[0111] This utility model embodiment also provides a vehicle, which includes the body described in any of the above embodiments.

[0112] After vehicle assembly, in the left-right direction (i.e., the thickness direction of the side structure 10), the wheel arch suspension mounting point area (i.e., the rear suspension support position) overlaps with the first connecting part 31. This provides better rigidity to the rear suspension support position. Additionally, seatbelt guide rings, seat mounting brackets, etc., can also achieve better rigidity by connecting with the side structure 10. Furthermore, the height of the upper end of the third connecting part 33, the area furthest from the first connecting part 31, is greater than the height of the rear door latch mounting point, thus providing better protection for rear occupants in a rear-side collision.

[0113] It should be understood that the above-mentioned settings can also be replaced in other ways, such as:

[0114] In other embodiments, the strength of the first plate 41, the second plate 42, the third plate 43, the fourth plate 51, the fifth plate 52, and the C-pillar plate 6 after molding can be the same, and all of them can be greater than the strength of the sixth plate 53 after molding. In a specific scenario, the strength of the first plate 41, the second plate 42, the third plate 43, the fourth plate 51, the fifth plate 52, and the C-pillar plate 6 after molding can be 1500 MPa, and the strength of the sixth plate 53 after molding can be 550 MPa.

[0115] In this embodiment, the thickness of the second plate 42 is equal to the thickness of the fourth plate 51 and greater than the thickness of the first plate 41; the thickness of the first plate 41 is equal to the thickness of the C-pillar plate 6; the thicknesses of the third plate 43, the fifth plate 52, and the sixth plate 63 are the same and greater than the thickness of the second plate 42. For example, in one scenario, the thickness of the first plate 41 is 1.0 mm, the thickness of the second plate is 1.4 mm, and the thickness of the third plate is 1.6 mm.

[0116] In other embodiments, the C-pillar structure 3 can also be a spliced ​​structure. For example, the C-pillar panel 6 is formed by splicing at least two panels, and then undergoes a thermoforming process to become the C-pillar structure 3.

[0117] In other embodiments, when the C-pillar structure 3 does not include the first connecting part 31, the lower end of the second connecting part 32 can be connected to the upper end of the third connecting part 33; when the C-pillar structure 3 does not include the second connecting part 32, the upper end of the first connecting part 31 can be connected to the rear end of the upper beam area 35 of the C-pillar.

[0118] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0119] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
