[0034] The following will describe the implementation of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0035] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0036] like Figures 1 to 13A vehicle body structure shown includes a cabin side beam, a shotgun and a pillar structure, wherein the upper end of the pillar structure is connected to the front end of the shotgun, and the lower part of the pillar structure is connected to the outer side of the front end of the cabin side beam. The pillar structure is in the shape of a triangular prism, and the inner edge of the cross section of the pillar structure is arranged along the length direction of the cabin side beam.

[0037] By adopting the above technical solution, when the vehicle has a small offset collision, the triangular prism-shaped column structure can enhance the side slip of the vehicle and improve the small offset collision performance of the vehicle; the column structure is connected between the front end of the cabin side beam and the front end of the shotgun, and can also improve the stiffness and strength of the body structure at the cabin side beam.

[0038] In some embodiments, Fig.12 and Fig.13 As shown, one edge of the cross section of the column structure on the outside is tilted inward from front to back, and the other edge of the cross section of the column structure on the outside is arranged facing forward or tilted outward from front to back. In a specific implementation, the cross section of the column structure is triangular, the inner edge of the triangle is arranged along the length direction of the cabin side beam, the rear edge of the two outer edges of the triangle is tilted inward from front to back, and the front edge of the two outer edges of the triangle is arranged facing forward or tilted outward from front to back. When the column structure is subjected to a rearward collision force, the column structure can transmit the collision force backward and inward, thereby enhancing the side slip of the vehicle.

[0039] In some embodiments, Figures 11 to 13 As shown, the lower part of the column structure is a first cavity structure arranged on the outer side of the front end of the cabin side beam, and the first cavity structure has a first cavity 6 inside. The upper part of the column structure is a second cavity structure, and the second cavity structure has a second cavity 7 inside. The lower end of the second cavity structure is connected to the upper end of the first cavity structure, and the upper end of the second cavity structure is connected to the front end of the shotgun. The above scheme uses two cavity structures to form the column structure, which can reduce the weight of the column structure while ensuring the rigidity and strength of the column structure, and also has the characteristics of being easy to implement.

[0040] In some embodiments, Figure 5 , Figure 6 and Fig.12As shown, the vehicle body structure includes a first component 202 fixedly connected to the outer side of the front end of the cabin side beam and a second component 104 fixedly connected to the front side of the first component 202. The first component 202, the second component 104 and the cabin side beam form a first cavity structure. In specific implementation, both the first component 202 and the second component 104 can be sheet metal parts, which has the characteristic of being easy to implement. As a preferred example, the second component 104 is a plate-shaped part connected to the front side of the first component 202 and the front side of the cabin side beam at the same time, and the second component 104 can improve the structural strength at the front end of the cabin side beam.

In specific implementation, the third component 203 and the fourth component 204 can both be sheet metal parts, which is easy to implement.

[0042] In some embodiments, Fig.11 and Fig.13 As shown, the third component 203 includes an extension portion extending backward from the second cavity structure, the upper side of the extension portion is connected to the shotgun, the lower side of the extension portion is connected to the cabin side beam, and the rear side of the extension portion is provided with a front shock tower connection portion. By adopting the above technical solution and providing the extension portion, the rigidity and strength of the body structure at the cabin side beam can be further improved.

[0043] In some embodiments, the vehicle body structure further includes a front shock tower 402, the upper portion of which is connected to the shotgun, and the lower portion of which is connected to the cabin side beam. By adopting the above technical solution, the front shock tower 402, the shotgun, the cabin side beam and the column structure are connected to form a stable and closed ring structure, which can further improve the rigidity and strength of the vehicle body structure at the cabin side beam, can reduce the use of reinforcements, and contribute to the lightweight of the vehicle. As a preferred example, the front side of the front shock tower 402 is fixedly connected to the front shock tower connecting portion on the extension portion.

[0044] In some embodiments, the front shock absorber tower 402 is an integrally formed casting. The cast front shock absorber tower 402 helps to improve the rigidity and strength of the body structure at the cabin side beam. In specific implementation, the front shock absorber tower 402 can be made by integral die casting. When the material of the front shock absorber tower 402 is a lightweight material such as aluminum alloy or magnesium alloy, the front shock absorber tower 402 also has the characteristic of being light in weight.

[0045] In some embodiments, the front end of the shotgun is connected to a first reinforcement 302, which can enhance the structural strength of the front end of the shotgun. As a preferred example, the first reinforcement 302 is provided with a fender mounting point or a fender mounting bracket mounting point.

Figure 7 and Figure 8 As shown, the Shotgun outer plate assembly 3 includes a Shotgun outer plate 301 and a first reinforcement member 302. Fig. 9 and Fig.10 As shown, the shock tower assembly 4 includes a shotgun inner plate 401 and a front shock tower 402. In specific manufacturing, the cabin side beam inner plate assembly 1, the cabin side beam outer plate assembly 2, the shotgun outer plate assembly 3 and the shock tower assembly 4 can be manufactured separately first, and then the cabin side beam inner plate assembly 1, the cabin side beam outer plate assembly 2, the shotgun outer plate assembly 3, the shock tower assembly 4 and the front end plate 5 are connected to form a vehicle body structure. The above technical solution has the characteristics of reasonable disassembly and easy manufacturing.
