[0030] Reference below Figure 1-Figure 3 The A-pillar structure 100 according to the embodiment of the present invention is described. By providing a reinforcement plate 14 connected to the A-pillar reinforcement plate 12, the overall structural strength of the A-pillar structure 100 can be improved, and an energy absorption cavity 17 is formed between the reinforcement plate 14 and the A-pillar reinforcement plate 12. The energy absorption cavity 17 forms a multi-cavity structure with the inner reinforcement cavity 15 and the outer reinforcement cavity 16, which can improve the stability of the force transmission channel during a collision, protect the safety of the vehicle structure, reduce the deformation of the passenger compartment, and improve the safety of the passengers.

[0031] like Figure 1-Figure 3 As shown, an A-pillar structure 100 according to an embodiment of the present invention includes: an upper A-pillar inner panel 11 , an A-pillar reinforcement panel 12 , an upper A-pillar outer panel 13 and a reinforcement panel 14 .

[0032] The upper A-pillar inner panel 11 , the A-pillar reinforcement panel 12 and the upper A-pillar outer panel 13 are sequentially connected in the inner and outer directions, and an inner reinforcement cavity 15 is formed between the upper A-pillar inner panel 11 and the A-pillar reinforcement panel 12 , and an outer reinforcement cavity 16 is formed between the upper A-pillar outer panel 13 and the A-pillar reinforcement panel 12 .

[0033] Specifically, the A-pillar structure 100 includes an upper A-pillar plate 1 and a lower A-main plate 2, and the upper A-pillar plate 1 includes an upper A-pillar inner plate 11, an A-pillar reinforcement plate 12, an upper A-pillar outer plate 13 and a reinforcing plate 14, wherein the inside-outside direction is along the transverse direction of the vehicle, that is, the Y direction, and the inside is a direction close to the center line of the vehicle, and the outside is a direction away from the center line of the vehicle, that is, the upper A-pillar inner plate 11, the A-pillar reinforcement plate 12 and the upper A-pillar outer plate 13 are sequentially connected from the inside to the outside along the transverse direction of the vehicle, wherein the A-pillar reinforcement plate 12 is a reinforcing component, and the upper A-pillar inner plate 11, the A-pillar reinforcement plate 12 and the upper A-pillar outer plate 13 can be connected by welding, which can enhance the strength between the upper A-pillar inner plate 11 and the upper A-pillar outer plate 13, so as to enhance the rigidity and strength of the A-pillar structure 100 and improve the safety of the vehicle in a collision, and the welding connection has high precision and good assembly effect, and the upper A-pillar inner plate 11, the A-pillar reinforcement plate 12 and the upper A-pillar outer plate 13 can be connected by fasteners such as bolts.

[0034] After the upper A-pillar inner panel 11, the A-pillar reinforcement plate 12 and the upper A-pillar outer panel 13 are connected, two reinforcement chambers can be formed, that is, an inner reinforcement chamber 15 is between the upper A-pillar inner panel 11 and the A-pillar reinforcement plate 12, and an outer reinforcement chamber 16 is between the upper A-pillar outer panel 13 and the A-pillar reinforcement plate 12, and the inner reinforcement chamber 15 and the outer reinforcement chamber 16 are separated by the A-pillar reinforcement plate 12, wherein the shapes of the inner reinforcement chamber 15 and the outer reinforcement chamber 16 can be configured as annular, and in other embodiments, they can also be configured as other shapes, and the inner reinforcement chamber 15 and the outer reinforcement chamber 16 extend along the length direction of the upper A-pillar plate 1, and the inner reinforcement chamber 15 and the outer reinforcement chamber 16 are hollow cavities for absorbing and dispersing the impact force of the collision, so as to enhance the structural strength of the upper A-pillar plate 1 and reduce the deformation of the upper A-pillar plate 1.

[0035] The reinforcement plate 14 is connected to the A-pillar reinforcement plate 12 and is located in the inner reinforcement cavity 15 or the outer reinforcement cavity 16 . An energy absorption cavity 17 is formed between the reinforcement plate 14 and the A-pillar reinforcement plate 12 .

[0036] Specifically, the upper A-pillar plate 1 extends in the front-to-back direction, the extension direction of the reinforcement plate 14 is consistent with the extension direction of the upper A-pillar inner plate 11, the reinforcement plate 14 is connected to the A-pillar reinforcement plate 12, and the reinforcement plate 14 can be connected to the A-pillar reinforcement plate 12 by welding. The welding connection has high strength, and the reinforcement plate 14 is used to support the A-pillar reinforcement plate 12, which can effectively enhance the structural strength of the A-pillar reinforcement plate, and further enhance the rigidity and strength of the upper A-pillar plate 1. In actual design, the reinforcement plate 14 can be located in the inner reinforcement cavity 15, or the reinforcement plate 14 is located in the outer reinforcement cavity 16, and the reinforcement plate 14 can be respectively arranged in the inner reinforcement cavity 15 and the outer reinforcement cavity 16. The arrangement method is not fixed and can be selectively arranged according to the actual space size.

[0037] After the reinforcement plate 14 is connected to the A-pillar reinforcement plate 12, an energy absorption cavity 17 is formed between the two. The energy absorption cavity 17 has the same function as the inner reinforcement cavity 15 and the outer reinforcement cavity 16, and is used to absorb and disperse the collision impact force, further enhance the structural strength of the upper A-pillar plate 1, and significantly reduce the deformation of the upper A-pillar plate 1.

[0038] Therefore, by adding the reinforcement plate 14, the strength of the upper A-pillar plate 1 can be effectively improved. During a vehicle collision, the impact force is transmitted to the upper A-pillar plate 1, and the impact force is absorbed and dispersed simultaneously through multiple cavity structures, making the force transmission process more stable, and can reduce the deformation of the passenger compartment, improve the collision performance of the vehicle, better protect the safety of the occupants, and has a simple structure and good use effect.

[0039] In some embodiments, the A-pillar reinforcement plate 12 has a receiving groove 121 open toward the upper A-pillar inner plate 11 or the upper A-pillar outer plate 13 , and the reinforcement plate 14 is installed in the receiving groove 121 and defines an energy absorption cavity 17 with the inner wall of the receiving groove 121 .

[0040] Specifically, the A-pillar reinforcement plate 12 may be provided with a receiving groove 121 open toward the upper A-pillar inner plate 11, or the A-pillar reinforcement plate 12 may be provided with a receiving groove 121 open toward the upper A-pillar outer plate 13. The arrangement methods are various and can be flexibly selected. Depending on the different receiving grooves 121, the arrangement methods of the reinforcement plate 14 are also different, such as Figure 1 As shown, the A-pillar reinforcement plate 12 has a receiving groove 121 open toward the upper A-pillar inner plate 11, which is used to install the reinforcement plate 14. The reinforcement plate 14 is connected to the inner wall of the A-pillar reinforcement plate 12, so that the reinforcement plate 14 and the inner wall of the receiving groove 121 define an energy absorption cavity 17. After the vehicle is hit, the energy absorption cavity 17 absorbs and disperses the impact force at the A-pillar reinforcement plate 12, and the reinforcement plate 14 supports the inner wall of the A-pillar reinforcement plate 12, thereby improving the structural strength of the A-pillar reinforcement plate 12.

[0041] Therefore, by setting the accommodating groove 121, the reinforcement plate 14 can be accurately installed on the A-pillar reinforcement plate 12, and such a setting can effectively utilize the internal space of the upper A-pillar plate 1, making the overall structure more compact without expanding the overall volume of the upper A-pillar plate 1, and the energy absorption cavity 17 can reduce the weight of the vehicle to meet the lightweight design requirements.

[0042] In some embodiments, the middle area of ​​the A-pillar reinforcement plate 12 in the up-down direction protrudes outward to define an inwardly open receiving groove 121 on the inner side of the A-pillar reinforcement plate 12 , and the top and bottom of the reinforcement plate 14 are both connected to the receiving groove 121 .

[0043] Specifically, Figure 1 As shown, in the up-down direction, the middle area of ​​the A-pillar reinforcement plate 12 is arranged to protrude outward, that is, the middle area of ​​the A-pillar reinforcement plate 12 protrudes toward the side close to the upper A-pillar outer plate 13. In this way, the A-pillar reinforcement plate 12 can be formed with a receiving groove 121 on the inner side facing the upper A-pillar inner plate 11, and the receiving groove 121 is open inward, and the outer contour of the reinforcement plate 14 is smaller than the inner contour of the receiving groove 121, which is conducive to the installation and matching of the two. During installation, the reinforcement plate 14 is accommodated in the inner side of the receiving groove 121, and the top and bottom of the receiving groove 121 are both fitted and connected to the receiving groove 121 to achieve the installation of the reinforcement plate 14.

[0044] Therefore, the middle area of ​​the A-pillar reinforcement plate 12 is protruded outward, and the reinforcement plate 14 is connected to the inner side of the A-pillar reinforcement plate 12, so that the space between the upper A-pillar outer plate 13 and the upper A-pillar inner plate 11 is reasonably utilized. The strength of the upper A-pillar plate 1 can be effectively improved by the A-pillar reinforcement plate 12 and the reinforcement plate 14, and the layout is simple and reasonable.

[0045] In some embodiments, the depth of the receiving groove 121 in the inner and outer directions is greater than the width of the reinforcing plate 14 in the inner and outer directions. Figure 1 As shown, in the inner and outer directions, the depth of the receiving groove 121 is large, and the depth of the receiving groove 121 is greater than the width of the reinforcing plate 14, so that the reinforcing plate 14 can be installed, and the reinforcing plate 14 will not completely occupy the space of the receiving groove 121, so that the reinforcing plate 14 is more flexible to install, and during the vehicle collision, the reinforcing plate 14 can disperse the impact force by deformation, thereby improving the collision performance of the vehicle. Among them, the width of the reinforcing plate 14 can be set to one-third of the depth of the receiving groove 121 to ensure the installation strength of the reinforcing plate 14 in the receiving groove 121.

[0046] In some embodiments, the reinforcement plate 14 is located in the inner reinforcement cavity 15, and the reinforcement plate 14 includes a first sub-plate 141, a second sub-plate 142 and a third sub-plate 143 that are bent and connected in sequence, the first sub-plate 141 and the third sub-plate 143 are respectively connected to the A-pillar reinforcement plate 12, and the second sub-plate 142 is respectively spaced apart from the upper A-pillar inner plate 11 and the A-pillar reinforcement plate 12 along the inner and outer directions.

[0047] Specifically, Figure 1 As shown, the inner wall of the accommodating groove 121 and the upper A-pillar inner plate 11 define an inner reinforcement cavity 15, and the reinforcement plate 14 is arranged in the inner reinforcement cavity 15, wherein the reinforcement plate 14 includes a first sub-plate 141, a second sub-plate 142 and a third sub-plate 143, wherein the first sub-plate 141, the second sub-plate 142 and the third sub-plate 143 are bent and connected in sequence, and in the up-down direction, the second sub-plate 142 can extend along the up-down direction, the first sub-plate 141 and the third sub-plate 143 are respectively located at the upper and lower ends of the second sub-plate 142, and the first sub-plate 141 and the third sub-plate 143 are respectively connected to the upper and lower sides of the A-pillar reinforcement plate 12, which can be connected by welding, and the strength of the welding connection is high, and the reinforcement plate 14 can be reliably connected to the A-pillar reinforcement plate 12 through the first sub-plate 141 and the third sub-plate 143.

[0048] In the inward and outward directions, the second sub-plate 142 is separated from the upper A-pillar inner plate 11 and the A-pillar reinforcement plate 12 respectively. In this way, the inner reinforcement cavity 15 can be divided into two cavities by the second sub-plate 142. The impact force can be absorbed and dispersed by the two cavities, and multiple force transmission channels are provided to ensure the stability of force transmission.

[0049] In actual processing, the reinforcing plate 14 can be formed by die casting or stamping.

[0050] In some embodiments, the first sub-plate 141 and the third sub-plate 143 are located on the same side of the second sub-plate 142 , and both the first sub-plate 141 and the third sub-plate 143 extend in the inward-outward direction and are inclined in opposite directions.

[0051] Specifically, the first sub-board 141 and the third sub-board 143 are bent and connected to the same side of the second sub-board 142, such as Figure 1 and Figure 2 As shown, the first sub-plate 141 and the third sub-plate 143 can be relatively distributed at both ends of the second sub-plate 142 and tilted in directions away from each other, that is, in the up and down directions, the first sub-plate 141 is connected to the upper end of the second sub-plate 142, and the third sub-plate 143 is connected to the lower end of the second sub-plate 142, and the first sub-plate 141 extends from the outside to the inside and tilts upward, and the third sub-plate 143 extends from the outside to the inside and tilts downward, and the angle between the first sub-plate 141 and the second sub-plate 142 and the angle between the third sub-plate 143 and the second sub-plate 142 can be the same or different, and at least parts of the upper and lower sides of the A-pillar reinforcement plate 12 are constructed to extend from the outside to the inside and tilt in directions that are relatively away from each other, so as to facilitate the fitting connection between the first sub-plate 141 and the third sub-plate 143 and the A-pillar reinforcement plate 12.

[0052] Therefore, by tilting the first sub-plate 141 and the third sub-plate 143, the upper and lower sides of the A-pillar reinforcement plate 12 can be effectively supported, the structural strength of the upper A-pillar plate 1 can be improved, and the stress can be effectively dispersed and the stress concentration can be reduced during the collision, thereby protecting the vehicle body structure from damage.

[0053] In some embodiments, the first sub-plate 141 is provided with a first fitting plane 1412 , and the third sub-plate 143 is provided with a second fitting plane 1432 . The first fitting plane 1412 and the second fitting plane 1432 are respectively fitted and connected to the A-pillar reinforcement plate 12 .

[0054] Specifically, the first fitting plane 1412 is arranged on a side of the first sub-panel 141 close to the A-pillar reinforcement plate 12, and the second fitting plane 1432 is arranged on a side of the third sub-panel 143 close to the A-pillar reinforcement plate 12, and the first fitting plane 1412 and the second fitting plane 1432 are relatively distributed, and the A-pillar reinforcement plate 12 is correspondingly provided with a first connecting plane and a second connecting plane on the upper and lower sides close to the reinforcement plate 14, and the first fitting plane 1412 and the second fitting plane 1432 are respectively fitted and connected with the first connecting plane and the second connecting plane, so that the first sub-panel 141 and the third sub-panel 143 can be fitted and connected with the A-pillar reinforcement plate 12, and they can be connected by welding, bonding or other methods.

[0055] Therefore, by setting up a fitting connection, the connection area between the first sub-panel 141 and the third sub-panel 143 and the A-pillar reinforcement plate 12 can be increased, so that the first sub-panel 141 and the third sub-panel 143 are tightly and reliably connected to the A-pillar reinforcement plate 12, which can improve the stability of the overall structure, and the fitting plane can be used as a path for energy transfer, which helps to more effectively transfer and disperse stress, reduce local stress concentration, so as to improve energy absorption efficiency and improve the durability of the structure.

[0056] In some embodiments, the first sub-plate 141 is provided with a plurality of first connection bosses 1411 spaced apart along the length direction, and the first fitting plane 1412 is formed on the first connection bosses 1411 .

[0057] Specifically, Figure 2 As shown, the first sub-plate 141 is provided with a first connecting boss 1411, and the first connecting boss 1411 protrudes from the surface of the first sub-plate 141. There are multiple first connecting bosses 1411, and the multiple first connecting bosses 1411 are spaced apart and distributed along the length direction of the first sub-plate 141, and each first connecting boss 1411 is formed with a first fitting plane 1412, and there are also multiple first fitting planes 1412. The protruding heights of the multiple first connecting bosses 1411 are the same, which can ensure that the heights of the multiple first fitting planes 1412 are consistent. In this way, the first sub-plate 141 is fitted and connected to the A-pillar reinforcement plate 12 through the multiple first fitting planes 1412, thereby improving the connection strength between the first sub-plate 141 and the A-pillar reinforcement plate 12 and improving its assembly accuracy, and avoiding abnormal noise.

[0058] Wherein, a first connecting boss 1411 is provided, and the first sub-plate 141 and the A-pillar reinforcement plate 12 may also be connected by other fasteners such as bolts and rivets.

[0059] In some other embodiments, the third sub-plate 143 is provided with a plurality of second connection bosses 1431 spaced apart along the length direction, and the second fitting plane 1432 is formed on the second connection bosses 1431 .

[0060] Specifically, Figure 2 As shown, the third sub-plate 143 is provided with a second connecting boss 1431, and the second connecting boss 1431 protrudes from the surface of the third sub-plate 143. There are multiple second connecting bosses 1431, and the multiple second connecting bosses 1431 are spaced apart and distributed along the length direction of the third sub-plate 143, and each second connecting boss 1431 is formed with a second fitting plane 1432, and there are also multiple second fitting planes 1432. The protruding heights of the multiple second connecting bosses 1431 are the same, which can ensure that the heights of the multiple second fitting planes 1432 are consistent. In this way, the third sub-plate 143 is fitted and connected to the A-pillar reinforcement plate 12 through the multiple second fitting planes 1432, which improves the connection strength between the third sub-plate 143 and the A-pillar reinforcement plate 12, and its assembly accuracy, and can avoid abnormal noise.

[0061] Wherein, a second connecting boss 1431 is provided, and the third sub-plate 143 and the A-pillar reinforcement plate 12 may also be connected by other fasteners such as bolts and rivets.

[0062] Furthermore, by setting a plurality of first connecting bosses 1411 on the first sub-plate 141, the structural strength of the first sub-plate 141 can be enhanced, and by setting a plurality of second connecting bosses 1431 on the third sub-plate 143, the structural strength of the third sub-plate 143 can be enhanced, thereby improving the structural strength of the reinforcement plate 14 and further improving the resistance to vehicle collision.

[0063] In some embodiments, the second sub-plate 142 is provided with a plurality of weight-reducing holes 1421 , which are spaced apart and distributed along the length direction of the second sub-plate 142 , and penetrate the second sub-plate 142 along the inside-out direction.

[0064] Specifically, the second sub-plate 142 is provided with a weight-reducing hole 1421, and the weight-reducing hole 1421 can be configured as a round hole, a bar hole, etc. Figure 2 As shown, the weight-reducing holes 1421 are constructed as circular holes, and there are multiple weight-reducing holes 1421, and the multiple weight-reducing holes 1421 are spaced apart and distributed along the length direction of the second sub-plate 142, and the multiple weight-reducing holes 1421 penetrate the second sub-plate 142 along the inside-outside direction, wherein the first sub-plate 141 and the third sub-plate 143 both extend along the inside-outside direction and are inclined in relatively divergent directions, then, the multiple weight-reducing holes 1421 do not interfere with the structures of the first sub-plate 141 and the third sub-plate 143, respectively, that is, they will not affect the structural strength of the first sub-plate 141 and the third sub-plate 143, wherein the weight-reducing holes 1421 can be set to four, five, six, etc.

[0065] Therefore, through the above arrangement, the structural strength of the second sub-plate 142 can be met, and the weight of the second sub-plate 142 can be reduced, thereby reducing the weight of the reinforcement plate 14 to meet the lightweight design requirements of the vehicle, and the weight-reducing hole 1421 can reduce the use of materials, thereby reducing costs.
