The embodiment provides an automobile, preferably, the automobile is an MPV automobile, and the automobile comprises a front structure of a vehicle body, which has better small offset collision performance.
Referring to fig. 1 to 4, the automobile includes a front side member 20 and a front rocker 40 connected to the rear end of the front side member 20, the front side member 20 and the front rocker 40 being substantially vertical, and a wheel cover plate 50 being connected between the front side member 20 and the front rocker 40. The front structure of the vehicle body includes an a-pillar member 10 and an upper short beam 15, the front and rear ends of the upper short beam 15 being connected to the front end of the front side member 20 and the front side of the a-pillar member 10, respectively, the inside of the upper short beam 15 and the inside of the a-pillar member 10 being connected to a wheel cover plate 50, the underside of the a-pillar member 10 also being connected to a front rocker 40.
With continued reference to fig. 1-4, the a-pillar member 10 includes an a-pillar 13 and a triangular window area 14 disposed below the a-pillar 13. Generally, the larger the size of the triangular window 14, the wider the viewable field it provides, whereas the larger the size of the triangular window 14, the weaker the energy absorbing and deformation resisting capabilities thereof, and thus the smaller the offset crash performance thereof. In order to obtain better small offset collision performance on the premise that the triangular window area 14 has a larger size, the lower side edge of the triangular window area 14 of the present embodiment is provided with a crumple structure, and the crumple structure is preferably a concave groove 16 (please refer to fig. 4) which is concave downward, the groove 16 is a V-shaped groove, and in other embodiments, the groove 16 is a U-shaped groove or a square groove or a groove with other shapes. In this embodiment, due to the existence of the groove 16, the lower side edge of the triangular window area 14 is more prone to crumple and deform than other side edges of the triangular window area 14, when the front side of the a pillar member 10 is extruded, the groove 16 can provide crumple space to guide the lower side edge of the triangular window area 14 to crumple, the lower side edge of the triangular window area 14 crumples and absorbs a large amount of collision energy, the collision energy received by other side edges of the triangular window area 14 is reduced, and the deformation degree is lower, so that the deformation degree of the whole triangular window area 14 is reduced, and the deformation degree of the a pillar 13 is further reduced. With the above-described scheme, the present embodiment can obtain a preferable small offset collision performance even if the triangular window area 14 is large in size. Of course, the crush structure is not limited to the grooves 16, but may be crush ribs, or a member having reduced strength than the other sides of the triangular window region 14, or the like.
In this embodiment, the a-pillar member 10 includes an a-pillar front plate 11 and an a-pillar rear plate 12, the a-pillar front plate 11 is welded to the rear end of the upper short beam 15, the a-pillar front plate 11 is connected to the a-pillar rear plate 12, preferably, the a-pillar front plate 11 is spliced to the a-pillar rear plate 12 to form a triangular window area 14 and an a-pillar 13, specifically, the a-pillar front plate 11 includes a first notch, the a-pillar rear plate 12 includes a second notch, the first notch and the second notch enclose the triangular window area 14, the lower side edge of the first notch and the lower side edge of the second notch are spliced and are connected by welding, the lower side edge of the first notch and the lower side edge of the second notch form the lower side edge of the triangular window area 14, the upper side edge of the first notch and the upper side edge of the second notch are spliced and are connected by welding, and the a-pillar 13 is formed by splicing the a-pillar front plate 11 and the upper side edge of the a-pillar rear plate 12. The vertical sides of the second notch constitute the rear sides of the triangular window area 14.
In the present embodiment, the lower side of the a-pillar front panel 11 and the lower side of the a-pillar rear panel 12 are both connected to the wheel cover panel 50. With reference to fig. 2 and 7, the lower side of the a-pillar back plate 12 is welded to the front girt 40, and in addition, the lower side of the a-pillar back plate 12 is connected to the front girt 40 of the automobile through an a-pillar patch 41, so that the connection strength between the a-pillar back plate 12 and the front girt 40 can be enhanced, and the transverse connection strength between the main force transmission structure at the front of the passenger compartment is improved, so that in a small offset collision, the tire is prevented from striking the a-pillar member 10, the welding spot between the front girt 40 and the a-pillar member 10 is prevented from tearing, the tire invades the passenger compartment, the structural rating is reduced, and meanwhile, after the connection strength of the main force transmission structure at the front of the passenger compartment is improved, the hub can be fully collapsed, and the small offset collision performance is further improved. Specifically, the a-pillar patch 41 is shaped like a Chinese character 'ji', and both ends of the a-pillar patch 41 are connected to the lower side of the a-pillar back plate 12 and the front girt 40 by bolts, respectively.
In this embodiment, the rigidity of the front a-pillar panel 11 is smaller than that of the rear a-pillar panel 12, so that when the front side of the a-pillar member 10 is pressed, the front a-pillar panel 11 collapses earlier than the rear a-pillar panel 12, and when the collision force is smaller, the front a-pillar panel 11 collapses and absorbs the impact momentum, while the rear a-pillar panel 12 can still maintain a smaller amount of collapse deformation, avoiding the complete collapse of the a-pillar member 10.

The thickness of the A-pillar rear inner plate is larger than that of the A-pillar front inner plate, the thickness of the A-pillar rear outer plate is larger than that of the A-pillar front outer plate, so that the rigidity of the A-pillar rear inner plate is larger than that of the A-pillar front inner plate, the rigidity of the A-pillar rear outer plate is larger than that of the A-pillar front outer plate, and finally, in this way, the rigidity of the A-pillar front plate 11 is smaller than that of the A-pillar rear plate 12. Of course, in other embodiments, the stiffness of the a-pillar rear inner panel, the a-pillar rear outer panel, the a-pillar front inner panel, and the a-pillar front outer panel may be changed by changing the shape, surface characteristics, materials, or other factors, thereby changing the stiffness of the a-pillar front panel 11 and the a-pillar rear panel 12. In other embodiments, the a-pillar front panel 11 and the a-pillar rear panel 12 may also be single-layer panels.
