Please refer to FIG. 1, FIG. 3, FIG. 4, and FIG. 5. The embodiment of the utility model provides a vehicle body pillar structure for improving the energy absorption and collision prevention performance of the vehicle, which includes a first pillar 1 for connecting between the lower cross beam 4 of the front cover of the vehicle and the upper longitudinal beam 5 and a second pillar 2 for connecting between the lower cross beam 4 of the front cover and the door sill beam 6 of the vehicle, wherein, along the length direction of the vehicle body, the first pillar 1 and the second pillar 2 are arranged front and back. It should be noted that the lower cross beam 4 of the front cover mentioned here refers to the support structure located at the top of the vehicle and used to support the top cover in the vehicle body structure; the upper longitudinal beam 5 refers to the front longitudinal beam reinforcement structure between the hinge column and the headlight cross beam, which is used to support the installation of components such as the front fender and the front hood; the door sill beam 6 refers to the longitudinal beams located on both sides of the front floor of the vehicle body, which are used to bear the weight of the vehicle body.

When the car is hit, in order to more quickly and effectively introduce the impact load to the front end of the car body, in this embodiment, the first pillar 1 and the second pillar 2 intersect and extend from the same end of the lower cross beam 4 of the front cover along the first direction and the second direction respectively, so that the same side of the car has a double pillar structure. Compared with the existing car that only has a single pillar structure at the same position, the two independent load transfer paths formed by the extension paths of the first pillar 1 and the second pillar 2 are more beneficial to improving the passive safety performance of the car. It should be noted that the first direction and the second direction mentioned here both refer to directions with an angle of 80 degrees to 100 degrees with the lower cross beam 4 of the front cover. Preferably, the first direction and the second direction are respectively perpendicular to the lower cross beam 4 of the front cover. In this way, the load transfer path from the first pillar 1 to the lower cross beam 4 of the front cover is the first right-angle transfer path, and the load transfer path from the second pillar 2 to the lower cross beam 4 of the front cover is the second right-angle transfer path, which is beneficial to efficiently transfer the impact load to the front longitudinal beam area, the side door frame column area and the front wheel hub area of the car.

For the convenience of passengers getting on and off the vehicle and to meet the requirements of ergonomic design, in this embodiment, the angle between the first direction and the second direction is an acute angle.

As shown in FIG. 2 , the first pillar 1 is in the shape of a long strip, including a first pillar inner plate 11 and a first pillar outer plate 12, wherein the first pillar inner plate 11 is in contact with the first pillar outer plate 12. The first pillar inner plate 11 is in the shape of a long strip, one end of which is connected to the lower cross beam 4 of the front cover, and the other end is connected to the upper longitudinal beam 5; the second pillar inner plate 12 is also in the shape of a long strip, one end of which is connected to the lower cross beam 4 of the front cover, and the other end is connected to the upper longitudinal beam 5. In this embodiment, in order to improve the vision of the occupants and reduce weight, the width of the first pillar inner plate 11 and the width of the first pillar outer plate 12 are gradually increased along the first direction.

In some embodiments, in order to allow the vehicle body structure to bear and absorb impact loads of different magnitudes when the vehicle collides, the first pillar 1 and the second pillar 2 may have different tensile strengths. Preferably, the tensile strength of the first pillar 1 is less than that of the second pillar 2. In this way, when the impact load energy is large, the first pillar 1 with a smaller tensile strength mainly functions to collapse and deform to absorb energy, while the second pillar 2 with a larger tensile strength will bear a smaller impact load, which is more beneficial to protecting the personal safety of the occupants in the vehicle.

Referring to FIG. 2 and FIG. 4 , the second pillar 2 is generally in a U-shaped structure, and includes a second pillar inner plate 21, a second pillar outer plate 22, and a second pillar reinforcement plate 23, wherein the second pillar reinforcement plate 23 is disposed between the second pillar inner plate 21 and the second pillar outer plate 22. The second pillar outer plate 22 is in a U-shaped structure, one end of which is connected to the lower cross beam 4 of the front cowl top cover, and the other end is connected to the door sill beam 6, and includes a second pillar outer plate top horizontal section 221, a second pillar outer plate middle vertical section 222, and a second pillar outer plate bottom horizontal section 223, wherein the width of the second pillar outer plate middle vertical section 222 first decreases and then increases along the direction from the second pillar outer plate bottom horizontal section 223 to the second pillar outer plate top horizontal section 221. The second pillar reinforcement plate 23 is a T-shaped structure, one end of which is connected to the lower cross beam 4 of the front cover, and the other end is connected to the door sill beam 6. It includes a top horizontal section 231 of the second pillar reinforcement plate and a middle vertical section 232 of the second pillar reinforcement plate, wherein the width of the middle vertical section 232 of the second pillar reinforcement plate gradually decreases from the bottom to the top. The second pillar inner plate 21 is a Y-shaped structure, which is arranged in the upper half of the second pillar outer plate 22, and one end is connected to the lower cross beam 4 of the front cover, and includes a first extension section 211, a second extension section 212 and a third extension section 213. It should be noted that the extension directions of the first extension section 211, the second extension section 212 and the third extension section 213 are different from each other.

In this embodiment, for the purpose of vibration isolation to improve the NVH (noise, vibration and harshness) of the automobile, the outer surfaces of the first extension section 211, the second extension section 212 and the third extension section 213 of the second pillar inner panel 21 are respectively provided with a first connecting portion, a second connecting portion and a third connecting portion, wherein the first connecting portion, the second connecting portion and the third connecting portion are all in the shape of a groove. Preferably, the first connecting portion, the second connecting portion and the third connecting portion are interconnected and perpendicular to each other.

In this embodiment, in order to improve the stability and reliability of the vehicle body pillar structure, the vehicle body pillar structure also includes a pillar connecting plate 3 connected between the first pillar 1 and the second pillar 2, as shown in Figures 1 and 2. The pillar connecting plate 3 includes a pillar connecting plate inner plate 31 and a pillar connecting plate outer plate 32 that is in contact with the pillar connecting plate inner plate 31.

It should be noted that the end of the pillar connecting plate outer plate 32 that fits with the pillar connecting plate inner plate 31 is a hook-shaped structure. When the first pillar 1, the second pillar 2 and the pillar connecting plate 3 are assembled, the first pillar 1, the second pillar 2 and the pillar connecting plate 3 will form a closed transfer path for transferring loads, which is beneficial for introducing loads into various parts of the front end of the vehicle body.

The embodiment of the utility model also discloses an automobile body structure, comprising a lower cross beam 4 of a front cover, an upper longitudinal beam 5, a door sill beam 6 and the automobile body pillar structure as described in the above embodiment, wherein a first pillar 1 of the automobile body pillar structure is connected between the lower cross beam 4 of the front cover and the upper longitudinal beam 5, and a second pillar 2 of the automobile body pillar structure is connected between the lower cross beam 4 of the front cover and the door sill beam 6, as shown in Figure 5, so that the above automobile body structure has the characteristics of more load transfer paths and better energy absorption and anti-collision performance.
