[0040] This disclosure provides a vehicle support column, with reference to Figure 1 As shown, the structure includes a first inner panel 11 and a second inner panel 12 connected together, a first reinforcing plate 21 and a second reinforcing plate 22 connected together, and a reinforcing frame 3. The first inner panel 11 and the first reinforcing plate 21 are connected to form the A-pillar structure of the vehicle, and the second inner panel 12 and the second reinforcing plate 22 are connected to form the B-pillar structure of the vehicle. A first mounting cavity is formed between the first inner panel 11 and the first reinforcing plate 21; a second mounting cavity is formed between the second inner panel 12 and the second reinforcing plate 22.

[0041] refer to Figure 2 As shown, the reinforcing frame 3 includes a first reinforcing rod 31 and a second reinforcing rod 32. The first reinforcing rod 31 is disposed in a first mounting cavity, and the second reinforcing rod 32 is disposed in a second mounting cavity. The first reinforcing rod 31 has a connecting portion, and one end of the second reinforcing rod 32 is connected to one side of the connecting portion. A first mounting bracket 41 is provided on the side of the connecting portion away from the second reinforcing rod 32. The first reinforcing rod 31 is connected to the first inner plate 11 or the first reinforcing plate 21 through the first mounting bracket 41.

[0042] The vehicle support column disclosed herein strengthens both the A-pillar and B-pillar structures of the vehicle by providing a first reinforcing rod 31 and a second reinforcing rod 32 in a first mounting cavity between the first inner plate 11 and the first reinforcing plate 21, and a second mounting cavity between the second inner plate 12 and the second reinforcing plate 22, respectively. Furthermore, the first reinforcing rod 31 and the second reinforcing rod 32 are connected, thus strengthening the overall A and B-pillar structure of the vehicle. The first reinforcing rod 31 is connected to the first inner plate 11 or the first reinforcing plate 21 via a first mounting bracket 41 adjacent to the connecting portion, making the connection between the reinforcing bracket 3 and the first inner plate 11 or the first reinforcing plate 21 more robust, thereby improving the rigidity and strength of the vehicle support column.

[0043] For example, the first inner panel 11 can be the A-pillar inner panel of a vehicle, located on the inner side of the vehicle; the second inner panel 12 can be the B-pillar inner panel of a vehicle, located on the inner side of the vehicle. The first inner panel 11 and the second inner panel 12 can be integrally formed, or they can be formed separately and then connected together by welding or riveting. The first reinforcing plate 21 can be the A-pillar reinforcing plate of a vehicle, located on the outer side of the vehicle; the second reinforcing plate 22 can be the B-pillar reinforcing plate of a vehicle, located on the outer side of the vehicle. The first reinforcing plate 21 and the second reinforcing plate 22 can be integrally formed, or they can be formed separately and then connected together by welding or riveting.

[0044] The first inner plate 11 is connected with the first reinforcing plate 21 to form a first mounting cavity. Exemplarily, the first inner plate 11 and the first reinforcing plate 21 can be connected and fixed by welding.

[0045] One end of the second reinforcing rod 32 is connected to one side of the connecting portion. Exemplarily, the one end of the second reinforcing rod 32 and the one side of the connecting portion are connected and fixed by welding.

[0046] Exemplarily, Figure 1 A structural schematic diagram of a vehicle support column is shown to clearly show the position and connection relationship of the reinforcing frame 3 in the first mounting cavity and the second mounting cavity, Figure 1 The structures that may block the reinforcing frame 3 are hidden, including but not limited to the first inner plate 11 and the second inner plate 12. Figure 2 A structure of the reinforcing frame 3 is shown. Figure 3 A structural schematic diagram of a vehicle support column is shown to clearly show the position and connection relationship of the reinforcing frame 3 in the first mounting cavity and the second mounting cavity,

[0047] The first reinforcing rod 31 is connected with the first inner plate 11 or the first reinforcing plate 21 through the first mounting bracket 41. Exemplarily, the first mounting bracket 41 is welded to the connecting portion of the first reinforcing rod 31 on the side away from the second reinforcing rod 32, as shown in Figure 1 、 Figure 2 .

[0048] In some embodiments, the second reinforcing rod 32 is connected to the side of the connecting portion close to the first reinforcing plate 21 and the second reinforcing plate 22, the side of the connecting portion close to the first inner plate 11 and the second inner plate 12 is provided with the first mounting bracket 41, and the first reinforcing rod 31 is connected with the first inner plate 11 through the first mounting bracket 41.

[0049] In other embodiments, as shown in Figure 1 、 Figure 2 , the second reinforcing rod 32 is connected to the side of the connecting portion away from the first reinforcing plate 21 and the second reinforcing plate 22, the side of the connecting portion close to the first reinforcing plate 21 and the second reinforcing plate 22 is provided with the first mounting bracket 41, and the first reinforcing rod 31 is connected with the first reinforcing plate 21 through the first mounting bracket 41.

[0050] In an exemplary embodiment of the present disclosure, as shown in Figure 1 、 Figure 2As shown, the reinforcing frame 3 further comprises a third reinforcing rod 33, which is also arranged in the second mounting cavity; one end of the third reinforcing rod 33 is connected to the side of the connecting portion to which the second reinforcing rod 32 is connected. Both the third reinforcing rod 33 and the second reinforcing rod 32 are arranged in the second mounting cavity, which can further strengthen the B-pillar structure of the vehicle.

[0051] As an example, one end of the second reinforcing rod 32 connected to the connecting portion faces the first direction; one end of the third reinforcing rod 33 connected to the connecting portion faces the second direction, and the first direction is different from the second direction. As shown in Figure 1 、 Figure 2 As an example, the second reinforcing rod 32 and the third reinforcing rod 33 have different orientations at the ends of the connecting portion, which can make the connection structure of the second reinforcing rod 32 and the third reinforcing rod 33 and the first reinforcing rod 31 more stable and less likely to deform. For example, the included angle a1 between the first direction and the second direction is 30°-45°.

[0052] In an exemplary embodiment of the present disclosure, the end of the first reinforcing rod 31 for connecting with the second reinforcing rod 32 and the third reinforcing rod 33 faces the third direction, and the included angle a2 between the first direction and the third direction is 85-95°; the included angle a3 between the second direction and the third direction is 45-60°. The angle (included angle a2) between the second reinforcing rod 32 and the connecting portion is closer to 90° than the angle (included angle a3) between the third reinforcing rod 33 and the connecting portion, so that the direction of the second reinforcing rod 32 matches the direction of the impact force perpendicular to the connecting portion, and the second reinforcing rod 32 has a more optimal reinforcing effect on the support pillar of the vehicle.

[0053] As an example, as shown in Figure 1 、 Figure 2 As an example, along the extension direction of the connecting portion, one end of the third reinforcing rod 33 close to the connecting portion faces the direction away from the other end of the first reinforcing rod 31, and one end of the second reinforcing rod 32 close to the connecting portion faces the direction close to the other end of the first reinforcing rod 31, which can make the connection structure of the second reinforcing rod 32 and the third reinforcing rod 33 and the first reinforcing rod 31 more stable and less likely to deform.

[0054] In an exemplary embodiment of the present disclosure, the minimum cross section of the second reinforcing rod 32 is larger than the maximum cross section of the third reinforcing rod 33. That is, the second reinforcing rod 32 is thicker than the third reinforcing rod 33, the second reinforcing rod 32 can have a main reinforcing effect on the B-pillar structure of the vehicle, and the third reinforcing rod 33 can have an auxiliary reinforcing effect on the B-pillar structure of the vehicle, while the third reinforcing rod 33 can improve the overall connection firmness of the reinforcing frame 3.

[0055] For example, one or more of the first reinforcing rod 31, the second reinforcing rod 32, and the third reinforcing rod 33 may be a solid beam structure or a tubular structure. For instance, the first reinforcing rod 31, the second reinforcing rod 32, and the third reinforcing rod 33 may all be tubes with uniform cross-sections, or the first reinforcing rod 31 may all be tubes with variable cross-sections, and the cross-sectional shape of the first reinforcing rod 31 may be adapted to the inner wall shape of the first mounting cavity, while the cross-sectional shapes of the second reinforcing rod 32 and the third reinforcing rod 33 may be adapted to the inner wall shape of the second mounting cavity.

[0056] In one exemplary embodiment of this disclosure, reference is made to Figure 1 , Figure 2 As shown, a second mounting bracket 42 is provided at the end of the first reinforcing rod 31 away from the connecting part. The first reinforcing rod 31 is connected to the first inner plate 11 or the first reinforcing plate 21 through the second mounting bracket 42. The first mounting bracket 41 and the second mounting bracket 42 fix the first reinforcing rod 31 at both ends, which can improve the firmness of the connection between the first reinforcing rod 31 and the first inner plate 11 or the first reinforcing plate 21.

[0057] refer to Figure 1 , Figure 2 As shown, a third mounting bracket 43 is provided at the end of the second reinforcing rod 32 away from the connecting part. The second reinforcing rod 32 is connected to the second inner plate 12 or the second reinforcing plate 22 through the third mounting bracket 43. The first mounting bracket 41 and the third mounting bracket 43 fix the second reinforcing rod 32 at both ends, which can improve the firmness of the connection between the second reinforcing rod 32 and the second inner plate 12 or the second reinforcing plate 22.

[0058] For example, the third reinforcing rod 33 is also connected to the third mounting bracket 43, and the third reinforcing rod 33 is connected to the second reinforcing plate 22 through the third mounting bracket 43. The first mounting bracket 41 and the third mounting bracket 43 respectively fix the opposite ends of the second reinforcing rod 32 and the third reinforcing rod 33, which can maintain the stability of the relative position between the second reinforcing rod 32 and the third reinforcing rod 33.

[0059] In one exemplary embodiment of this disclosure, reference is made to Figure 1 , Figure 2As shown, the second reinforcing rod 32 is also connected with the second inner panel 12 or the second reinforcing panel 22 through a fourth mounting bracket 44, which is located between the first mounting bracket 41 and the third mounting bracket 43 along the extension direction of the second reinforcing rod 32. The fourth mounting bracket 44 can further enhance the connection stability of the second reinforcing rod 32 on the second inner panel 12 or the second reinforcing panel 22. Meanwhile, the fourth mounting bracket 44 itself can also strengthen the structure of the vehicle B-pillar. Exemplarily, the third reinforcing rod 33 is also connected with the fourth mounting bracket 44. For example, the fourth mounting bracket 44 can be arranged at the water-cut structure position corresponding to the position of the window beam on the B-pillar.

[0060] Exemplarily, the first mounting bracket 41, the second mounting bracket 42, the third mounting bracket 43 and the fourth mounting bracket 44 can be arranged at the same side of the reinforcing frame 3 and fix the reinforcing frame 3 to the inner panel or the reinforcing panel of the vehicle support pillar, for example, according to the scheme shown in the drawings.

[0061] For example, the reinforcing frame 3 is fixed to the reinforcing panel of the vehicle support pillar through the first mounting bracket 41, the second mounting bracket 42, the third mounting bracket 43 and the fourth mounting bracket 44. Specifically:

[0062] The first reinforcing rod 31 is connected with the first reinforcing panel 21 through the first mounting bracket 41 and the second mounting bracket 42, the first reinforcing rod 31 is welded to the first mounting bracket 41 at the side of the first mounting bracket 41 away from the first reinforcing panel 21, and the first reinforcing rod 31 is welded to the second mounting bracket 42 at the side of the second mounting bracket 42 away from the first reinforcing panel 21.

[0063] The second reinforcing rod 32 is connected with the second reinforcing panel 22 through the third mounting bracket 43 and the fourth mounting bracket 44, the second reinforcing rod 32 is welded to the third mounting bracket 43 at the side of the third mounting bracket 43 away from the second reinforcing panel 22, and the second reinforcing rod 32 is welded to the fourth mounting bracket 44 at the side of the fourth mounting bracket 44 away from the second reinforcing panel 22.

[0064] The third reinforcing rod 33 is connected with the second reinforcing panel 22 through the third mounting bracket 43 and the fourth mounting bracket 44, the third reinforcing rod 33 is welded to the third mounting bracket 43 at the side of the third mounting bracket 43 away from the second reinforcing panel 22, and the third reinforcing rod 33 is welded to the fourth mounting bracket 44 at the side of the fourth mounting bracket 44 away from the second reinforcing panel 22.

[0065] As can be understood by those skilled in the art, for the case that the reinforcing frame 3 is fixed to the inner panel of the vehicle support pillar through the first mounting bracket 41, the second mounting bracket 42, the third mounting bracket 43 and the fourth mounting bracket 44, the above-mentioned embodiments can be referred to for description, which will not be repeated here.

[0066] In an exemplary embodiment of the present disclosure, the second mounting cavity is further provided with a reinforcing bracket 5, one side of the reinforcing bracket 5 being connected with the second reinforcing rod 32 and the third reinforcing rod 33, and the other side of the reinforcing bracket 5 being connected with the second inner plate 12. Referring to Figure 4 , a cross-sectional view at B-B in FIG. 4 is shown. Figure 3 Exemplarily, the reinforcing bracket 5 is opposite to the fourth mounting bracket 44 in the direction between the second inner plate 12 and the second reinforcing plate 22, and the reinforcing bracket 5 is located between the first mounting bracket 41 and the third mounting bracket 43 in the extension direction of the second reinforcing rod 32.

[0067] The reinforcing bracket 5 can also connect the second reinforcing rod 32 and the third reinforcing rod 33 with the second inner plate 12. For example, the second reinforcing rod 32 and the third reinforcing rod 33 are welded to the fourth mounting bracket 44, and the fourth mounting bracket 44 is welded to the second reinforcing plate 22; the second reinforcing rod 32 and the third reinforcing rod 33 are respectively adhered to the reinforcing bracket 5, and the reinforcing bracket 5 is adhered to the second inner plate 12, so that the fixing of the second reinforcing plate 22, the reinforcing frame 3 and the second inner plate 12 is more firm, and the reinforcing effect on the vehicle support column is more optimal.

[0068] Referring to Figure 4 , specifically, the reinforcing bracket 5 can include a first leg 51, a second leg 52 and a support portion 53, and the support portion 53 is located between the first leg 51 and the second leg 52. In the direction between the second inner plate 12 and the second reinforcing plate 22, the support portion 53 protrudes towards the second reinforcing plate 22, and the first leg 51 and the second leg 52 protrude towards the second inner plate 12.

[0069] The side of the first leg 51 away from the support portion 53 is provided with a first adhesive layer 54, the side of the second leg 52 away from the support portion 53 is provided with a second adhesive layer 55, and the side of the support portion 53 away from the first leg 51 and the second leg 52 is provided with a third adhesive layer 56. The reinforcing bracket 5 is adhered to the second inner plate 12 through the first adhesive layer 54 and the second adhesive layer 55; and the reinforcing bracket 5 is adhered to the second reinforcing rod 32 and the third reinforcing rod 33 through the third adhesive layer 56.

[0070] For example, the reinforcing bracket 5 can include a nylon composite material, for example, a nylon 6 or nylon 66 matrix with 30%-50% glass fiber or carbon fiber reinforcement to form a high-strength composite material. The first adhesive layer 54, the second adhesive layer 55 and the third adhesive layer 56 can be expansion adhesive, for example, two-component epoxy resin with foaming agent and hollow glass microspheres.

[0071] In the assembly of the reinforcing bracket 5, the reinforcing bracket 5 can be initially fixed on the second inner plate 12 by bolts, buckles or other structures. The first adhesive layer 54 and the second adhesive layer 55 can have gaps with the second inner plate 12, and the third adhesive layer 56 can have gaps with the second reinforcing rod 32 and the third reinforcing rod 33. Exemplarily, the reinforcing bracket 5 is provided with a first hook on the side close to the second inner plate 12, and the second inner plate 12 is provided with a corresponding second hook on the inner side. The first hook cooperates with the second hook to preliminarily connect the reinforcing bracket 5 to the second inner plate 12.

[0072] After the welding of the second inner plate 12 and the second reinforcing plate 22 is completed, the first adhesive layer 54, the second adhesive layer 55 and the third adhesive layer 56 are expanded by controlling the process parameters to fill the gaps and achieve the bonding and fixing with the second inner plate 12 and the second reinforcing rod 32 and the third reinforcing rod 33. This not only improves the connection firmness of the second reinforcing rod 32, the third reinforcing rod 33, the second inner plate 12 and the second reinforcing plate 22, but also further improves the strength and rigidity of the B-pillar after the expansion of the first adhesive layer 54, the second adhesive layer 55 and the third adhesive layer 56.

[0073] According to another aspect of the present disclosure, a vehicle is also provided, which comprises the vehicle support pillar of any one of the preceding aspects. The vehicle of the present disclosure has a support pillar with higher strength and rigidity, which is beneficial to the passenger compartment integrity in the collision scenario and has higher safety.
