[0072] like Figure 1-19 As shown, according to the first aspect of an embodiment of the present application, a vehicle body structure 100 is provided, including two first tube beams 1-1, two frame longitudinal beams 2, two rear beams 3, two front longitudinal beams 1-10, two rear longitudinal beams 3-4, and two door sill beams 2-3, which are spaced apart in the vehicle width direction, and the two first tube beams 1-1 are connected to each other, the two frame longitudinal beams 2 are connected to each other, and the two rear beams 3 are connected to each other; in the vehicle length direction, the first tube beam 1-1, the frame longitudinal beam 2 and the rear beam 3 located on the same side in the vehicle width direction are connected in sequence, and the front longitudinal beam 1-10, the door sill beam 2-3 and the rear longitudinal beam 3-4 are connected in sequence; the rear beam 3 is connected to the rear longitudinal beam 3-4 located on the same side in the vehicle width direction at one end away from the frame longitudinal beam 2, and the front longitudinal beam 1-10, the door sill beam 2-3 and the rear longitudinal beam 3-4 are connected in sequence; the rear beam 3 is connected to the rear longitudinal beam 3-4 located on the same side in the vehicle width direction at one end away from the frame longitudinal beam 2, and the first tube beam 1-1 is connected to the front longitudinal beam 1-10 located on the same side in the vehicle width direction at one end away from the frame longitudinal beam 2.

[0073] like Figure 1-Figure 3 As shown, the vehicle body structure 100 includes two first tube beams 1-1, two frame longitudinal beams 2, two rear beams 3, two front longitudinal beams 1-10, two rear longitudinal beams 3-4, and two sill beams 2-3 that are spaced apart in the vehicle width direction. That is, the two first tube beams 1-1 are distributed on both sides in the vehicle width direction, the two front longitudinal beams 1-10 are distributed on both sides in the vehicle width direction, the two rear longitudinal beams 3-4 are distributed on both sides in the vehicle width direction, and the two sill beams 2-3 are distributed on both sides in the vehicle width direction.

[0074] To further illustrate, in the length direction of the vehicle, the first tubular beam 1-1, the frame longitudinal beam 2 and the rear beam 3 located on the same side in the width direction of the vehicle are connected in sequence, and the front longitudinal beam 1-10, the door sill beam 2-3 and the rear longitudinal beam 3-4 located on the same side in the width direction of the vehicle are connected in sequence; and the two first tubular beams 1-1 are connected to each other in the width direction of the vehicle, the two frame longitudinal beams 2 are connected to each other in the width direction of the vehicle, and the two rear beams 3 are connected to each other in the width direction of the vehicle.

[0075] Therefore, the two first tube beams 1-1, the two frame longitudinal beams 2 and the two rear beams 3 are connected to form a frame structure. The first tube beam 1-1, the front longitudinal beam 1-10, the frame longitudinal beam 2, the door sill beams 2-3, the rear beam 3 and the rear longitudinal beams 3-4 located on the same side of the vehicle width direction form a frame structure. The frame structure is also formed on the other side of the vehicle width direction. The two front longitudinal beams 1-10, the two door sill beams 2-3 and the two rear longitudinal beams 3-4 form a frame structure; the above-mentioned four frame structures are respectively located at the upper, lower, left and right four directions of the vehicle body structure 100, and together provide structural strength for the vehicle body structure 100, so that they can better play the role of deformation energy absorption when the vehicle body collides with the front and rear, thereby reducing the impact on the vehicle body structure 100.

[0076] Preferably, the first tube beam 1 - 1 and the rear beam 3 are made of aluminum alloy. On the one hand, the weight of the vehicle body can be reduced by about 20%-30%; on the other hand, the aluminum alloy can better play the role of deformation and energy absorption when the vehicle body collides with the front and rear, thereby reducing the impact on the vehicle body structure 100.

[0077] Preferably, the vehicle frame longitudinal beam 2 is designed with a multi-material mixture of high-performance composite materials, aluminum alloys, and ultra-high-strength hot-formed steel, and the most suitable material is selected at a suitable position according to the different performance requirements of different areas of the vehicle frame longitudinal beam 2, so as to improve the structural strength of the passenger compartment at the vehicle frame longitudinal beam 2.

[0078] like Figure 4-6 As shown, the first tube beam 1-1 is connected to the vehicle frame longitudinal beam 2. The first tube beam 1-1 is connected to the vehicle frame longitudinal beam 2 located on the same side in the vehicle width direction.

[0079] In this embodiment, the vehicle body structure 100 also includes two front joints 2-8 spaced apart along the width direction of the vehicle, and the first tube beam 1-1 is connected to the vehicle frame longitudinal beam 2 located on the same side in the width direction of the vehicle through the corresponding front joints 2-8; wherein the front joints 2-8 are an integrally formed structure.

[0080] like Figure 4-6 As shown, the vehicle body structure 100 also includes two front joints 2-8, and the two front joints 2-8 are spaced apart along the vehicle width direction. The first tube beam 1-1 is connected to the vehicle frame longitudinal beam 2 through the front joint 2-8, and the connection between the first tube beam 1-1, the front joint 2-8 and the vehicle frame longitudinal beam 2 is performed on the same side in the vehicle width direction. The first tube beam 1-1 is connected to the front joint 2-8. The first tube beam 1-1 is provided with a first connecting hole in the vehicle width direction, the front joint 2-8 is provided with a second receiving groove 2-8a, and the second receiving groove 2-8a is provided with a second connecting hole in the vehicle width direction. The first tube beam 1-1 is partially embedded in the second receiving groove 2-8a, and the first connecting hole coincides with the second connecting hole, and is connected by bolts in the vehicle width direction.

[0081] To further explain, the front joint 2-8 is integrally formed by a high vacuum die-casting process, forming a connecting joint between the first tube beam 1-1 and the frame longitudinal beam 2 at the front position of the upper part of the vehicle body structure 100. When the vehicle body structure 100 is subjected to external force, the front joint 2-8 bears the load and force transmission functions.

[0082] In this embodiment, the vehicle body structure 100 also includes two A-pillar assemblies 2-2 spaced apart along the width direction of the vehicle, the upper end of the A-pillar assembly 2-2 is connected to the vehicle frame longitudinal beam 2 located on the same side of the width direction of the vehicle, and the lower end of the A-pillar assembly 2-2 is connected to the rocker beam 2-3 located on the same side of the width direction of the vehicle.

[0083] like Figure 3 As shown, the vehicle body structure 100 further includes two A-pillar assemblies 2-2, which are spaced apart along the vehicle width direction. The upper end of the A-pillar assembly 2-2 is connected to the vehicle frame longitudinal beam 2 located on the same side in the vehicle width direction, and the lower end of the A-pillar assembly 2-2 is connected to the sill beam 2-3 located on the same side in the vehicle width direction. The vehicle frame longitudinal beam 2 is connected to the sill beam 2-3 through the A-pillar assembly 2-2, thereby improving the structural strength of the side of the vehicle body structure 100.

[0084] In this embodiment, the A-pillar assembly 2-2 is provided with a first receiving groove, and the front joint 2-8 is arranged in the first receiving groove. At the connection between the A-pillar assembly 2-2 and the vehicle frame longitudinal beam 2, the A-pillar assembly 2-2 is provided with a first receiving groove, and the front joint 2-8 is embedded in the first receiving groove to provide an installation space for the front joint 2-8, so as to prevent the front joint 2-8 from being exposed and affecting the installation of other components of the vehicle body structure 100.

[0085] In this embodiment, the vehicle body structure 100 also includes two front wheel covers 1-2 spaced apart along the vehicle width direction. In the vehicle height direction, the upper side of the front wheel covers 1-2 is connected to the first tube beam 1-1 located on the same side of the vehicle width direction, and the lower side of the front wheel covers 1-2 is connected to the front longitudinal beam 1-10 located on the same side of the vehicle width direction.

[0086] The vehicle body structure 100 further includes two front wheel covers 1-2, which are spaced apart in the vehicle width direction. The upper side of the front wheel covers 1-2 is connected to the first pipe beam 1-1 located on the same side in the vehicle width direction, and the lower side of the front wheel covers 1-2 is connected to the front longitudinal beam 1-10 located on the same side in the vehicle width direction. Therefore, the first pipe beam 1-1 and the front longitudinal beam 1-10 are connected through the front wheel covers 1-2, thereby improving the structural strength of the front side of the vehicle body structure 100.

[0087] In this embodiment, the vehicle body structure 100 also includes a front panel 2-5, the two front wheel covers 1-2 are connected to the front side of the front panel 2-5, and the frame longitudinal beam 2, the door sill beam 2-3 and the front longitudinal beam 1-10 of the front panel 2-5 are connected.

[0088] like Figure 6 As shown, the vehicle body structure 100 further includes a dash panel 2-5, which is arranged along the vehicle width direction. Two front wheel covers 1-2 arranged at intervals in the vehicle width direction are both connected to the front side of the dash panel 2-5. The front wheel cover 1-2 has a mounting plane with a third connecting hole, and the dash panel 2-5 has a mounting plane with a nut embedded therein. The mounting plane of the front wheel cover 1-2 abuts against the mounting plane of the dash panel 2-5, and is connected to the nut on the dash panel 2-5 through the third connecting hole by a bolt, thereby fixing the front wheel cover 1-2 to the dash panel 2-5.

[0089] To further illustrate, the front panel 2-5 is also connected to the vehicle frame longitudinal beam 2, the door sill beam 2-3 and the front longitudinal beam 1-10, thereby forming a closed force transmission loop in the vehicle width direction, thereby being able to improve the structural strength of the side of the vehicle body structure 100.

[0090] In this embodiment, the vehicle body structure 100 also includes two upper longitudinal beams 1-6 and two front pillars 1-7 arranged at intervals along the vehicle width direction; the front pillars 1-7 extend along the height direction, and the front pillars 1-7 are connected to the front longitudinal beam 1-10 located on the same side of the vehicle width direction, and in the vehicle length direction, the front pillars 1-7 are located in front of the front wheel cover 1-2; the two ends of the upper longitudinal beam 1-6 are respectively connected to the front pillars 1-7 and the front wheel cover 1-2 located on the same side of the vehicle width direction.

[0091] like Figure 7 As shown, the vehicle body structure 100 further includes two upper longitudinal beams 1-6 and two front pillars 1-7, the two upper longitudinal beams 1-6 are arranged at intervals along the vehicle width direction, the two front pillars 1-7 are arranged at intervals along the vehicle width direction, and the front pillars 1-7 extend along the vehicle height direction. Among them, one end of the front pillar 1-7 is connected to the front longitudinal beam 1-10 located on the same side of the vehicle width direction, the other end of the front pillar 1-7 is connected to one end of the upper longitudinal beam 1-6 located on the same side of the vehicle width direction, and the other end of the upper longitudinal beam 1-6 is connected to the front wheel cover 1-2 located on the same side of the vehicle width direction. Therefore, the front wheel cover 1-2, the front pillar 1-7, the upper longitudinal beam 1-6 and the front longitudinal beam 1-10 located on the same side of the vehicle width direction form a frame structure, so that the structural strength of the front sides of the vehicle body structure 100 can be improved.

[0092] In this embodiment, in the vehicle height direction, the upper longitudinal beam 1-6 is spaced apart from the front longitudinal beam 1-10 located on the same side in the vehicle width direction. That is, the upper longitudinal beam 1-6 and the front longitudinal beam 1-10 located on the same side in the vehicle width direction are at different heights. The upper longitudinal beam 1-6 and the front longitudinal beam 1-10 are connected through the front pillar 1-7 and the front wheel housing 1-2, thereby forming a frame structure on both sides in the vehicle width direction to improve the structural strength of the vehicle body structure 100.

[0093] In this embodiment, Figure 7 As shown, the vehicle body structure 100 further includes a first cross beam 1-8, and both ends of the first cross beam 1-8 are respectively connected to the two front longitudinal beams 1-10. The first cross beam 1-8 is arranged along the vehicle width direction, and the first cross beam 1-8 is connected to the two front longitudinal beams 1-10, so that the structural strength of the front longitudinal beam 1-10 in front of the vehicle body structure 100 can be improved.

[0094] In this embodiment, Figure 7 As shown, the vehicle body structure 100 further includes a second cross beam 1-9, and the two ends of the second cross beam 1-9 are respectively connected to the two front wheel housings 1-2; in the front-rear direction of the vehicle, the first cross beam 1-8 is located in front of the second cross beam 1-9.

Before assembly, the longitudinal beam 2 of the vehicle frame needs to be coated with room temperature curing structural glue avoiding the position of the nut hole, and then the lower cross beam 2-7 of the rear panel and the rear side panel assembly 2-6 are pressed forward against the longitudinal beam 2 of the vehicle frame, and then the bolts are tightened. The longitudinal beam 2 of the vehicle frame and the front strut 3-1, the rear longitudinal beam 3-4 and the lower cross beam 2-7 of the rear panel, and the rear side panel assembly 2-6 are connected to form an integral structure through multiple points, multiple surfaces and glue and screw composite connection, wherein the screw connection has the characteristics of high connection strength, good reliability and stability, and the glue connection can isolate the connected dissimilar materials to prevent electrochemical corrosion.

Thus, the structural strength of the bottom of the vehicle body structure 100 can be improved.

[0142] It is further explained that the reinforcing plates 3-9 preferably use high-rigidity, low-density materials, such as carbon fiber composite laminates or sandwich panels, which can greatly improve the bottom stiffness of the body structure 100 and reduce the torsional deformation of the body structure 100 when the vehicle is driving, thereby improving the handling stability.

Fixing in two directions can improve the connection strength between the front longitudinal beam front section 1-4 and the front longitudinal beam rear section 2-1. The connecting member can be a bolt, a screw or other connecting member. The rear longitudinal beam 3-4 includes a rear longitudinal beam front section and a rear longitudinal beam rear section, and the rear longitudinal beam front section is connected to the rear longitudinal beam rear section.
