[0002] The B-pillar is a pillar located between the front door and the rear door in the side of the vehicle. Its overall structure is strong at the top and weak at the bottom. It is arranged like this because during a side collision of the vehicle, if the upper section of the B-pillar is strong, the impact on the head of the occupants in the vehicle can be avoided or reduced; while the lower section of the B-pillar is weak, so the deformation is large, the energy absorbed is large, and the lower part is protected by the vehicle seat, so the harm to the occupants in the vehicle is relatively small.

[0003] In the existing B-pillar structure, the upper section of the B-pillar is mainly reinforced by the B-pillar outer panel reinforcement plate. If the strength of the reinforcement plate is insufficient and it needs to cooperate with the surrounding parts, the only way is to increase the thickness of the B-pillar upper section reinforcement plate or improve the material. However, these two methods have limited reinforcement effects on the upper section of the B-pillar and may cause welding difficulties. Utility Model Content

[0043] Embodiment 1

[0044] The present embodiment relates to a vehicle body pillar reinforcement structure, which is applied in a vehicle body pillar, and is particularly suitable for being installed in the upper section of a vehicle B-pillar, and can effectively improve the structural strength of this part, thereby improving the side collision performance of the vehicle, and can effectively protect the head safety of occupants in the vehicle.

[0045] Based on the above design concept, an exemplary structure of the vehicle body pillar reinforcement structure in the application state of the present embodiment is as follows: Figure 1 As shown, the vehicle body pillar reinforcement structure is mainly used to be installed in the vehicle body pillar to improve the structural strength of the vehicle body pillar. Since the upper section of the B-pillar of the vehicle body needs a higher structural strength, the following description is based on the vehicle body pillar of this embodiment as the vehicle body B-pillar.

[0046] In order to facilitate a better understanding of the present embodiment, it is first necessary to explain that the B-pillar is a pillar of the vehicle body side located between the front door and the rear door of the vehicle body. The existing B-pillar, in terms of the height direction of the vehicle, includes a B-pillar upper section and a B-pillar lower section connected together up and down, and in terms of the width direction of the vehicle, it mainly includes a B-pillar outer panel and a B-pillar inner panel. A cavity is formed between the B-pillar outer panel and the B-pillar inner panel, and the cavity extends along the height direction of the vehicle. The vehicle body pillar reinforcement structure of the present embodiment is located in the cavity of the B-pillar upper section.

[0047] In the existing B-pillar structure, in order to strengthen the structural strength of the upper section of the B-pillar, a B-pillar outer panel reinforcement plate 6 is further provided in the cavity of the upper section of the B-pillar. Figure 1 That is, the vehicle body pillar reinforcement structure of this embodiment is installed on the inner side of the B-pillar outer panel reinforcement plate 6 (that is, the side of the B-pillar outer panel reinforcement plate 6 facing the vehicle interior). Figure 1 As long as a cavity arranged along the height direction of the vehicle is provided in the B-pillar of the B-pillar outer panel reinforcement plate 6 shown, the vehicle body pillar structure of this embodiment can be adopted. During specific installation, each reinforcement plate can be connected to the existing structure of the B-pillar, for example, connected to the B-pillar outer panel.

[0048] In addition, the vehicle body pillar reinforcement structure of this embodiment can be applied not only to the upper section of the B-pillar of the vehicle body, but also to other pillars, such as the C-pillar or the A-pillar of the vehicle body, by bending the connecting beam as needed to facilitate the connection between the reinforcement plate and the vehicle body pillar.

[0049] The exemplary structure of the vehicle body pillar reinforcement structure of this embodiment is as follows: Figure 2 As shown, it mainly includes a reinforcing plate and a connecting beam, wherein the reinforcing plates are multiple and spaced apart along the height direction of the vehicle, and any adjacent reinforcing plates are connected by a connecting beam, specifically by seam welding.

[0050] As a preferred embodiment, the reinforcing plate is used to connect with the B-pillar outer panel reinforcing plate 6 of the B-pillar, and the connecting beam is arranged at a distance from the B-pillar outer panel reinforcing plate 6 in the vehicle width direction. As in this embodiment, the vehicle body pillar reinforcement structure is arranged on the inner side of the B-pillar outer panel reinforcing plate 6, which is welded and connected to the B-pillar outer panel reinforcing plate 6 by the following upper reinforcing plate 1, middle reinforcing plate 2 and lower reinforcing plate 3, while the upper connecting beam 4 and lower connecting beam 5 are arranged at a distance from the B-pillar outer panel reinforcing plate 6 in the vehicle width direction.

[0051] In the above structure, the vehicle body pillar structure is connected to the B-pillar outer panel reinforcement plate 6 through various reinforcement plates, which is conducive to assembly using welding technology. The connecting beam and the B-pillar outer panel reinforcement plate 6 are arranged at a distance, and there is no need to add large-area welding points, and it is not easy to cause collision noise between the connecting beam and the B-pillar outer panel reinforcement plate 6.

[0052] As a preferred embodiment, the plurality of reinforcing plates include an upper reinforcing plate 1, a middle reinforcing plate 2 and a lower reinforcing plate 3 arranged in sequence from top to bottom, and the connecting beam includes an upper connecting beam 4 connecting the upper reinforcing plate 1 and the middle reinforcing plate 2, and a lower connecting beam 5 connecting the middle reinforcing plate 2 and the lower reinforcing plate 3. Such an arrangement is more suitable for being arranged at the upper section of the B-pillar, so that the structural strength of the B-pillar meets the requirements, and the weight and cost will not be increased too much due to the addition of the reinforcing structure.

[0053] It should be noted that, in this embodiment, three reinforcing plates are used as an example for explanation. In other implementations, the number of reinforcing plates can be set to other values ​​as needed, such as 2, 4, 5, etc.

[0054] As a preferred embodiment, each reinforcing plate is provided with a support portion 7, which is formed by a local reinforcing plate being recessed to one side, and the end of each connecting beam is overlapped on the corresponding reinforcing plate's support portion 7. With such a configuration, the support portion 7 is easy to process and form, and is convenient for stably and reliably connecting the connecting beams, and has the effect of strengthening the structural strength of the reinforcing plate.

[0055] like Figure 3 As shown, the support portion 7 on the upper reinforcing plate 1 is formed by the middle portion of the third folding plate 103 described below being recessed toward the side facing the interior of the vehicle to form a plane, and the end of the connecting beam is overlapped on this plane and connected by welding.

[0056] For example Figure 4 As shown, the upper and lower parts of the middle reinforcing plate 2 are provided with protruding parts protruding toward the inside of the vehicle, and the supporting part 7 is recessed from the middle of the protruding part toward the outside of the vehicle to form a groove, so that the end of the connecting beam can be embedded in the groove and connected by welding. Figure 5 As shown, the structure of the support portion 7 on the lower reinforcing plate 3 is similar to Figure 4The structure is similar to that in , and will not be repeated here.

[0057] As a preferred embodiment, at least one of the reinforcing plates is provided with reinforcing ribs 8, that is, it is feasible to provide reinforcing ribs 8 on any one, any two or any two or more reinforcing plates, which can improve the structural strength of the reinforcing plate itself and improve the effect of reinforcing the B-pillar structure.

[0058] like Figure 3 As shown, the reinforcing rib 8 is formed by a part of the upper reinforcing plate 1 protruding outward to one side, the number of the reinforcing ribs 8 is 3, and the length directions of the three reinforcing ribs 8 all extend along the height direction of the vehicle. Figure 5 As shown, two reinforcing ribs 8 are also provided near the supporting portion 7. It should be noted that the reinforcing ribs 8 may be formed by partially concavely forming the upper reinforcing plate 1 to one side, and the number and shape of the reinforcing ribs 8 may be limited according to actual needs. In addition to being provided on the upper reinforcing plate 1, the reinforcing ribs 8 may also be provided on the middle reinforcing plate 2, and may be arranged according to actual needs.

[0059] As a preferred embodiment, still refer to Figure 3 As shown, the upper reinforcement plate 1 includes a first folding plate 101, a second folding plate 102 and a third folding plate 103 connected in sequence, an angle is set between the first folding plate 101 and the second folding plate 102, and an angle is set between the second folding plate 102 and the third folding plate 103. The first folding plate 101 and the third folding plate 103 are used to be connected with the B-pillar outer panel reinforcement plate 6, and a gap is set between the second folding plate 102 and the B-pillar outer panel reinforcement plate 6, and the gap extends along the length direction of the vehicle.

[0060] Here, the upper reinforcement plate 1 includes a first folding plate 101, a second folding plate 102 and a third folding plate 103, which are convenient for connection with the B-pillar outer panel reinforcement plate 6, and the cross-section of the connection portion between the second folding plate 102 and the B-pillar outer panel reinforcement plate 6 is annular, which can better improve the structural strength of the B-pillar and better absorb energy to improve the side impact performance of the B-pillar.

[0061] It should be noted that each reinforcement plate mentioned in this embodiment has as large a fitting area as possible with the B-pillar outer panel reinforcement plate 6 to facilitate the arrangement of multiple welding points, thereby improving the reliability of the connection between the vehicle body pillar reinforcement structure and the B-pillar outer panel.

[0062] Finally, it should be noted that the reinforcing plate and the connecting beam are preferably connected by welding, which has good structural strength and is easy to process. In addition, pin connection, screw connection, riveting, bonding, etc. are also possible.

[0063] As a preferred embodiment, the two opposite sides of the B-pillar outer panel reinforcement plate 6 are provided with a first flange 601, and the two opposite sides of the middle reinforcement plate 2 are provided with a second flange 201. The first flange 601 and the second flange 201 on the corresponding sides are fitted and connected, and the specific connection adopts a welding process.

[0064] Here, the second flange 201 provided can improve the structural strength and rigidity of the middle reinforcing plate 2 itself, and is beneficial to improving the structural strength and rigidity of the overall vehicle body pillar reinforcement structure; it can also increase the contact area between the middle reinforcing plate 2 and the B-pillar outer panel reinforcing plate 6, which is beneficial to the arrangement of welding points, and improves the connection reliability between the middle reinforcing plate 2 and the B-pillar outer panel reinforcing plate 6.

[0065] As a preferred embodiment, each second flange 201 is provided with a clearance hole 202 on one side, and the clearance hole 202 is specifically arranged in the middle of the second flange 201 in the vehicle height direction. Figure 3 As shown, due to the provision of the clearance hole 202, the second flanges 201 on both sides are completely divided into two sections. The position of the clearance hole 202 can facilitate the welding and connection between the B-pillar outer panel reinforcement plate 6 and the B-pillar outer panel and the B-pillar inner panel, and the clearance hole 202 is arranged in the middle position of the second flange 201 in the vehicle height direction, which can ensure the connection reliability of the middle reinforcement plate 2 and the B-pillar outer panel reinforcement plate 6.

[0066] As a preferred embodiment, at least one of the reinforcement plates is provided with a positioning portion 9, which is used to define the installation position of the vehicle body pillar reinforcement structure on the B-pillar outer panel reinforcement plate 6, so as to improve the assembly speed and assembly quality.

[0067] In a preferred embodiment, the positioning portion 9 is specifically a positioning hole. Figure 3 As shown in FIG. 1 , a positioning hole is provided on the first folding plate 101 of the upper reinforcing plate 1. Figure 5 As shown, a positioning hole is provided at the lower portion of the lower reinforcing plate 3 .

[0068] It should be understood that by providing positioning holes on the upper reinforcing plate 1 and the lower reinforcing plate 3, and arranging the positioning points at positions close to both ends of the vehicle body pillar reinforcement structure, it is possible to achieve a better effect of improving the positioning accuracy. In addition, positioning holes can of course be arranged at other positions or on other reinforcing plates. In addition, the positioning portion 9 can be set as other structures, such as notches, positioning protrusions, etc., in addition to being set as positioning holes.

[0069] As a preferred implementation, each connecting beam is provided with a cavity, and the cavity specifically extends along the length direction of the connecting beam, so that the connecting beam is light in weight and has a good effect of strengthening the structural strength of the B-pillar.

[0070] As a preferred embodiment, the cross-sectional shapes of the connecting beams are different, so that suitable connecting beams can be arranged according to strength or space requirements, and the functional requirements of reducing weight and improving structural strength can be well met.

[0071] As in the present embodiment, the cross-sectional shape of the upper connecting beam 4 is preferably a strip hole, and the length direction of the strip hole is along the length direction of the vehicle. The cross-sectional shape of the lower connecting beam 5 is preferably a circular hole. In addition, the shape of the connecting beam can also be set to other shapes, such as oval, square, triangle, etc.

[0072] The vehicle body pillar reinforcement structure of the utility model changes the cross-sectional shape in the upward direction of the vehicle height. For example, in the present embodiment, plate-shaped and ring-shaped structures are arranged alternately below the vehicle body pillar. Different parts with different strength requirements at different heights can be reinforced separately as needed. This has a good effect of strengthening the strength of the B-pillar structure, while meeting the requirements of weight reduction and cost reduction.

[0073] Compared with the existing larger reinforcement plate structure, the body pillar reinforcement structure is easy to assemble in the B-pillar, and there is no need to worry about the problem of adding a larger plate structure that cannot be welded. It can also better strengthen the structural strength of the B-pillar, improve the stiffness and mode of the B-pillar, and thus effectively ensure the safety of the passengers in the vehicle when used on the vehicle.
