The vehicle adopts a bearing type vehicle body structure, and is characterized in that an independent vehicle frame is not arranged, the whole vehicle body component completely participates in bearing, and the vehicle body is mainly a rigid frame structure formed by assembling and welding a bottom plate, a framework, an inner skin, an outer skin and other components. The vehicle body can be roughly divided into an engine compartment, a passenger compartment and a luggage compartment, and the main stressed components are four-beam six-column, namely two front longitudinal beams, two rear longitudinal beams, two A columns, two B columns and two C columns. The A column, the B column and the C column of the vehicle are important components of a passenger compartment of a load-bearing vehicle body and are main stress components on the vehicle, so that high design requirements are imposed on the A column, the B column and the C column.

The a-pillars are pillars on both sides of the front windshield, and are located between the engine compartment and the passenger compartment. In addition to the function of connecting the roof and the door, the a-pillar of the vehicle plays a very important role in protecting the passenger compartment from deformation and preventing the intrusion of wheels, suspensions, and the like into the passenger compartment during a frontal collision at the front of the vehicle.

As shown in fig. 1 to 4, the a-pillar assembly 10 includes an outer panel 11, an inner panel 12, a first reinforcing structure 14, and a second reinforcing structure 15.

The outer panel 11 serves as one of structural members of the a-pillar assembly 10 for connecting the vehicle upper side member 20 and the vehicle cabin side member 30, and the outer panel 11 may be made of a ductile ordinary steel. The specific structure of the outer panel 11 will be described later.

The inner panel 12 serves as another structural member of the a-pillar assembly 10 for connecting the vehicle upper side member 20 and the vehicle cabin side member 30, and the inner panel 12 may be made of high-strength steel or hot-formed steel.

The first inner plate 120 and the outer plate 11 together form an accommodating cavity 13, that is, the first inner plate 120 and the outer plate 11 together enclose the accommodating cavity 13. For example, the cross section of the first inner panel 120 is shaped like an M in a direction perpendicular to the extending direction of the inner panel 12 and the outer panel 11, the cross section of the first outer panel 111 (described below) of the outer panel 11 is shaped like an arch, the first inner panel 120 and the first outer panel 111 of the outer panel 11 enclose the accommodating cavity 13, and the cross section of the accommodating cavity 13 may be shaped like a square. The first inner plate 120 with the M-shaped structure is matched with the first outer plate 11 with the arch structure to form the closed accommodating cavity 13 with the square structure, so that the overall structural strength of the a-pillar assembly 1 is effectively improved.

At least part of the first reinforcing structure 14 is located in the part of the receiving cavity 13 corresponding to the first connecting section 121, that is, the first reinforcing structure 14 may be located in part of the receiving cavity 13 corresponding to the first connecting section 121, and the first reinforcing structure 14 may also be located in whole in the part of the receiving cavity 13 corresponding to the first connecting section 121. It should be noted that when the portion of the first reinforcing structure 14 is located in the portion of the accommodating cavity 13 corresponding to the first connecting section 121, the remaining portion of the first reinforcing structure 14 may be located outside the accommodating cavity 13 formed by the outer plate 11 and the first inner plate 120 together, and of course, the remaining portion of the first reinforcing structure 14 may also be located in the portion of the accommodating cavity 13 between the first connecting section 121 and the second connecting section 122.

The first reinforcing structure 14 is connected to the first connecting section 121, wherein the first reinforcing structure 14 and the first connecting section 121 can be detachably connected or non-detachably connected to each other to fix the position of the first reinforcing structure 14 relative to the first connecting section 121. For example, when the first reinforcing structure 14 is detachably connected to the first connecting section 121, the first reinforcing structure 14 can be connected to the first connecting section 121 by gluing or welding; when the first reinforcing structure 14 is connected to the first connecting section 121 in a non-detachable manner, the first reinforcing structure 14 can be connected to the first connecting section 121 in a screw connection, a clamping connection, or a combination thereof.

At least part of the second reinforcing structure 15 is located in the part of the accommodating cavity 13 corresponding to the second connecting section 122, that is, the second reinforcing structure 15 may be located in part of the accommodating cavity 13 corresponding to the second connecting section 122, and the second reinforcing structure 15 may also be located in whole in the part of the accommodating cavity 13 corresponding to the second connecting section 122. It should be noted that when the portion of the second reinforcing structure 15 is located in the portion of the accommodating cavity 13 corresponding to the second connecting section 122, the remaining portion of the second reinforcing structure 15 may be located outside the accommodating cavity 13 formed by the outer plate 11 and the first inner plate 120 together, and of course, the remaining portion of the second reinforcing structure 15 may also be located in the portion of the accommodating cavity 13 between the first connecting section 121 and the second connecting section 122.

The second reinforcing structure 15 is connected to the second connecting section 122, wherein the second reinforcing structure 15 and the second connecting section 122 can be detachably connected or non-detachably connected to each other, so as to relatively fix the positions of the second reinforcing structure 15 and the second connecting section 122. For example, when the second reinforcing structure 15 is connected to the second connecting section 122 in a non-detachable manner, the second reinforcing structure 15 can be connected to the second connecting section 122 by gluing or welding, but not limited thereto; when the second reinforcing structure 15 is detachably connected to the second connecting section 122, the second reinforcing structure 15 may be connected to the second connecting section 122 by, but not limited to, screwing, clamping, or a combination of screwing and clamping.

The second reinforcing structure 15 is disposed at a distance from the first reinforcing structure 14, i.e., the second reinforcing structure 15 is disposed independently of the first reinforcing structure 14, and ends of the first reinforcing structure 14 and the second reinforcing structure 15 that are close to each other are spaced apart by a certain distance in the extending direction of the inner panel 12.

It should be noted that at least one of the first reinforcing structure 14 and the second reinforcing structure 15 may be made of a carbon fiber composite material, and the strength of the first reinforcing structure 14 and/or the second reinforcing structure 15 made of the carbon fiber composite material is up to 3000 mpa, which is much higher than the strength of the first reinforcing structure 14 and/or the second reinforcing structure 15 made of a material such as hot-formed steel or high-strength steel, so as to effectively improve the bending resistance and torsion resistance of the a-pillar assembly 10, increase the safety during vehicle collision, and effectively reduce the injury of the vehicle collision to drivers and passengers. The connection between the first reinforcing structure 14 and the first connecting section 121 and the connection between the second reinforcing structure 15 and the second connecting section 122 may be the same or different.

Based on the a-pillar assembly 10 in the embodiment of the present application, the first reinforcing structure 14 and the second reinforcing structure 15 form a segmented structure, the first reinforcing structure 14 is used for reinforcing the structural strength of the connection position between the outer plate 11 and the first inner plate 120 and the vehicle upper longitudinal beam 20, the second reinforcing structure is used for reinforcing the structural strength of the connection position between the outer plate 11 and the second inner plate and the vehicle cabin longitudinal beam 30, the specific position of the vehicle body of the vehicle is reinforced in a targeted structure, the vibration response sensitivity in the vehicle driving process can be effectively reduced, the road noise is reduced, and the NVH characteristic of the vehicle is effectively improved. Of course, the weight of the entire vehicle body can be reduced compared to the case where the reinforcement structure is provided over the entire inner panel 12, and the overall cost of the vehicle body can be reduced.

The specific values of the preset range are not limited, so that designers can reasonably design the vehicle according to actual needs, and it can be understood that the values of the preset range are different for vehicles of different models. For example, the value of the preset range may be, but is not limited to, 200 mm or more and 300 mm or less. In the design, the first reinforcing structure 14 and the second reinforcing structure 15 are designed to have difference in length dimension, so that the structural strength of the connecting position of the first connecting section 121 and the vehicle body upper side member 20 of the vehicle is different from the structural strength of the connecting position of the second connecting section 122 and the vehicle cabin side member 30 of the vehicle, the vibration frequencies of the first connecting section 121 and the second connecting section 122 are different, and the design of local frequency avoidance (different vibration frequencies) is realized, thereby effectively avoiding the first connecting section 121 and the second connecting section 122 from generating resonance.

That is, the first straight line segment 141, the bent segment 142 and the second straight line segment 143 are sequentially connected to form a first reinforcing structure 14 having an L-like shape. In this design, by designing that the part of the first straight line segment 141 extends out of the accommodating cavity 13, the part of the first straight line segment 141 outside the accommodating cavity 13 can be used for connecting with the upper side frame 20 of the vehicle, so that the first straight line segment 141 can play a good role in reinforcing the upper side frame 20 of the vehicle, and the connection stability of the first reinforcing structure 14 and the upper side frame 20 of the vehicle can be enhanced; by designing the bending section 142 and the second straight section 143 to be connected with the first connecting section 121, the bending section 142 and the second straight section 143 have a good reinforcing effect on the first inner plate 120; the first straight line section 141 and the second straight line section 143 are transitionally connected through the bent section 142, so that the overall shape of the first reinforcing structure 14 is matched with the shape of the connecting position of the A-pillar assembly 10 and the upper side member 20 of the vehicle body, and the structural strength of the connecting position of the A-pillar assembly 10 and the upper side member 20 of the vehicle body is effectively improved.

For example, for the first reinforcing structure 14, the length of the first straight line segment 141 may be 300 mm, and the sum of the lengths of the bent segment 142 and the second straight line segment 143 may be 260 mm. The plurality of first ribs 145 include a plurality of first protrusions, which may be rectangular protrusions or circular protrusions, and a plurality of first grooves, which may be rectangular grooves or circular grooves.

In this design, by designing the second reinforcing bodies 152 on the second reinforcing plate 151, the second reinforcing bodies 152 function as reinforcing ribs, and the structural strength of the second reinforcing structure 15 can be effectively enhanced; by designing all the second reinforcing bodies 152 to have different sizes, the local resonance generated on the second reinforcing plate 151 by the road excitation energy can be effectively reduced, so that the vibration sensitivity of the second reinforcing structure 15 is effectively reduced, and the road noise is reduced; by designing all the second reinforcing bodies 152 to have different shapes, it is possible to effectively reduce the local resonance generated by the road excitation energy on the second reinforcing plate 151, and to effectively reduce the vibration sensitivity of the second reinforcing structure 15, thereby reducing the road noise.
