[0002] Automobile safety performance testing has not only become a national standard and industry hotspot, but also an important means of market promotion for automobile manufacturers.

[0003] NCAP is the standard for safety testing in various countries. NCAP first appeared in the United States in 1978. After entering the 1990s, Europe and Japan also established their own NCAP systems, which were respectively called E-NCAP in Europe and J-NCAP in Japan. Among them, E-NCAP in Europe is the most influential and representative.

[0004] In China, there are C-NCAP and China Insurance Research Institute that evaluate collision safety performance. The conditions included in frontal high-speed collision are full head-on collision, 40% frontal offset collision and 25% small frontal offset collision.

[0005] When a vehicle collides, the structural strength of the A-pillar is crucial to the safety of the vehicle.

[0006] The common structure of general vehicle models is that the upper and lower hinge positions of the door ring reinforcement plate are welded to the upper hinge reinforcement plate of the box-shaped A-pillar and the lower hinge reinforcement plate of the A-pillar respectively. This structure can meet the safety collision requirements and the performance requirements of the front door installation points. However, during a small offset collision, the A-pillar is deformed greatly as the cross-section is subjected to greater force. The welds on the edge of the stop are easily torn, resulting in uncontrollable deformation. These risks lead to the urgent need to strengthen the rigidity of the A-pillar cavity.

[0007] At the same time, after searching, the existing patent 201821687003.7 - A car A-pillar reinforcement structure and car can achieve the reinforcement of the A-pillar, but the overall structure is relatively simple, and the increase in strength or rigidity is limited.

[0035] The following is a description of the preferred embodiment with reference to the accompanying drawings.

[0036] Provide further detailed explanation.

[0037] An A-pillar reinforcement structure is connected to the A-pillar body; the A-pillar reinforcement structure includes a hinge

[0038] Chain reinforcement plate 6, hinge reinforcement plate 6 is distributed at the upper hinge mounting point and the lower hinge mounting point of the A-pillar body;

[0039] Both ends of the hinge reinforcement plate 6 are pressed on the upper hinge installation point and the lower hinge installation point at the same time; the utility model sets an integral hinge reinforcement plate 6, so that the inner side of the A-pillar body is equivalent to being embedded with an integral plate, which can increase the overall structural strength and rigidity of the A-pillar assembly to a certain extent; increase the deformation resistance of the A-pillar; at the same time, the integral hinge reinforcement plate 6 can reduce the number of A-pillar assembly parts, utilize actual assembly, and reduce assembly procedures.

[0040] The A-pillar reinforcement structure disclosed in the utility model is mainly connected to the A-pillar body, and is used to increase the overall rigidity and strength of the A-pillar assembly.

[0041] Specifically, the A-pillar reinforcement structure disclosed in the present invention is mainly connected to the A-pillar body; the A-pillar reinforcement structure includes a hinge reinforcement plate 6, which is arranged on the inner side of the A-pillar body, and the hinge reinforcement plate 6 is distributed at the upper hinge mounting point and the lower hinge mounting point of the A-pillar body; both ends of the hinge reinforcement plate 6 are simultaneously pressed on the upper hinge mounting point and the lower hinge mounting point; in the existing A-pillar structure, the traditional hinge is stronger. The plate is divided into an upper hinge reinforcement plate 6 and a lower hinge reinforcement plate 6; although the split traditional hinge reinforcement plate 6 can increase the rigidity and strength of the A-pillar assembly to a certain extent, the overall arrangement is relatively cumbersome. At the same time, during a small offset collision, due to the large cross-sectional force, the overall deformation of the A-pillar is large, and the stop edge welding point is easily torn, resulting in uncontrollable deformation; the present invention designs the traditional split hinge reinforcement plate 6 into an integral reinforcement plate, that is, the hinge reinforcement plate 6 in the present invention is an integral plate structure; and extends from the upper side of the A-pillar body to the lower side of the A-pillar body; it can greatly improve the overall structural rigidity of the A-pillar body.

[0042] Furthermore, in the present invention, the A-pillar reinforcement structure also includes a reinforcement bracket 8 arranged on the A-pillar body; the setting of the reinforcement bracket 8 allows the inner cavity of the A-pillar body to form a support, which can better ensure the overall structural rigidity of the A-pillar assembly; at the same time, in the present invention, the horizontal projection of the A-pillar body is in the shape of a "J", that is, the A-pillar body has an inner cavity structure, and the reinforcement bracket 8 can be arranged in the inner cavity, thereby increasing or decreasing the rigidity and strength of the A-pillar assembly, and also facilitating the subsequent connection and assembly between the A-pillar body and the A-pillar vertical plate 5.

[0043] At the same time, in the utility model, the reinforcing bracket 8 includes at least two single-body brackets 7, and the adjacent single-body brackets 7 are distributed at intervals; the number of single-body brackets 7 included in the reinforcing bracket 8 can be selected and set according to actual needs. A commonly used implementation scheme is to set two single-body brackets 7, which are distributed at intervals at the upper and lower ends of the A-pillar body. Such a setting can not only increase the rigidity and strength of the inner cavity of the A-pillar body, but also facilitate the subsequent connection of the A-pillar vertical plate 5.

[0044] In addition, in the utility model, each single bracket 7 has a vertical cross-section in the shape of a "J"; based on such a configuration, the utility model can ensure the structural strength and rigidity of the single bracket 7, because such a design makes the single bracket 7 equivalent to a box structure, thereby ensuring its own rigidity.

[0045] In addition, in the utility model, the single-body bracket 7 includes a bracket body, and the bracket body includes an end panel 71, and side panels 73 are provided on opposite sides of the end panel 71, and a connecting flange 72 is provided on the end of the side panel 73 away from the end panel 71; the end panel 71 is distributed on the side of the side panel 73 away from the A-pillar body; the side panel 73 is connected to the A-pillar body through the connecting flange 72; the end panel 71 and the A-pillar body tend to be arranged parallel to each other, and the side panel 73 plays a role of raising and extending, and the arrangement of the connecting flange 72 facilitates the welding and assembly of the single-body bracket 7 on the A-pillar body.

[0046] In the utility model, a side panel 73 is provided at the upper and lower ends of the end panel 71, and a connecting flange 72 is provided at the end of the side panel 73 away from the end panel 71. This arrangement makes the vertical cross-section of the bracket body present a "J" shape; thereby making the single-body bracket 7 itself form a box structure; thereby ensuring the overall strength and rigidity of the single-body bracket 7.

[0047] Furthermore, in the present invention, the single-body bracket 7 is connected to the A-pillar vertical plate 5 through a fastening portion; the fastening portion includes a mounting hole arranged on the single-body bracket 7; the present invention facilitates the connection between the single-body bracket 7 and the A-pillar vertical plate 5 through the arrangement of the fastening portion; at the same time, a fastening nut 10 is provided at the periphery of the mounting hole of the single-body bracket 7, and the fastening nut 10 is coaxially arranged with the mounting hole; the arrangement of the fastening nut 10 facilitates the subsequent threading of the fastening bolt 11 on the single-body bracket 7, thereby also facilitating the subsequent connection of the A-pillar vertical plate 5.

[0048] An A-pillar assembly includes an A-pillar body, on which an A-pillar reinforcement structure is provided; the A-pillar body is connected to an A-pillar riser 5 via the A-pillar reinforcement structure; in the utility model, the provision of the A-pillar reinforcement structure can not only facilitate the connection between the A-pillar body and the A-pillar riser 5, but also greatly increase the overall structural strength and rigidity of the A-pillar assembly.

[0049] Furthermore, in the utility model, the A-pillar body includes a side outer panel 1, and a door ring reinforcement plate 2 is provided inside the side outer panel 1; the hinge reinforcement plate 6 in the A-pillar reinforcement structure is connected to the door ring reinforcement plate 2; in the utility model, the horizontal projections of the side outer panel 1 and the door ring reinforcement plate 2 both form a "X" shape, which makes the A-pillar body have an inner cavity structure. Such a setting facilitates the laying of the hinge reinforcement plate 6 and forms a box-like structure, which can better ensure the overall structural strength of the A-pillar assembly.

[0050] Furthermore, in the utility model, the hinge reinforcement plate 6, the door ring reinforcement plate 2 and the corresponding single bracket 7 in the A-pillar reinforcement structure are connected by three-layer welding; such a connection method can reduce the welding process and improve the welding efficiency while ensuring the stable connection of each component.

[0051] A welding spot 9 is formed at the welding points of the middle hinge reinforcement plate 6 , the door ring reinforcement plate 2 and the single body bracket 7 .

[0052] specific:

[0053] The A-pillar assembly disclosed in the utility model mainly includes an A-pillar reinforcement structure; the A-pillar reinforcement structure includes an A-pillar body, a hinge reinforcement plate 6 and a reinforcement bracket 8; and the A-pillar body includes a side outer panel 1, and a door ring reinforcement plate 2 is arranged inside the side outer panel 1.

[0056] By adding an I-shaped bracket in the A-pillar cavity and using M8 bolts to connect the upper and lower car bodies, the rigidity of the A-pillar section is enhanced and the structure's ability to resist deformation is greatly improved.

[0057] Obviously, the specific implementation of the present invention is not limited by the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
