[0029] Please also read Figures 1 to 9 The D-pillar reinforcement structure and the vehicle provided by the utility model are now described. The D-pillar reinforcement structure comprises a side window inner panel 1 and a D-pillar reinforcement panel upper section 2, the D-pillar reinforcement panel upper section 2 is connected to the outer side of the side window inner panel 1, the D-pillar reinforcement panel upper section 2 has a first boss portion 3 protruding outward of the vehicle body, the first boss portion 3 is located at the rear side of the side window, and a second boss portion 4 protruding outward of the vehicle body is provided on the first boss portion 3.

[0030] Compared with the prior art, the D-pillar reinforcement structure provided in the present embodiment is formed by enclosing a side window inner panel 1 and an upper portion 2 of the D-pillar reinforcement plate. A first boss portion 3 is provided on the upper portion 2 of the D-pillar reinforcement plate, and a second boss portion 4 is provided on the first boss portion 3 to form a double-layer step effect, which is convenient for improving the structural rigidity and strength of the component, and structurally reinforcing the area behind the rear side window close to the D-pillar, which can effectively strengthen the force transmission channel in the rear area of ​​the side beam, improve the torsional rigidity and structural strength of the entire vehicle, and thus improve the overall safety performance of the vehicle.

[0031] In the present embodiment, the side window inner panel 1 and the D-pillar reinforcement plate upper section 2 are mutually enclosed and connected from the inside and outside, and a cavity structure is formed between the side window inner panel 1 and the D-pillar reinforcement plate upper section 2. The arrangement of the above structure can, on the one hand, play a role in strengthening the structure of the D-pillar, and on the other hand, provide sufficient space for the installation of other components, thereby facilitating the structural layout of other components in the above cavity.

[0032] Specifically, the edge positions of the side window inner panel 1 and the upper section 2 of the D-pillar reinforcement panel are extended to the adjacent side and connected, so that the two are separated by a certain distance in the inner and outer directions of the vehicle body, thereby conveniently forming the above-mentioned cavity structure and strengthening the structure of the D-pillar to a certain extent.

[0033] On the basis of the above structure, a first boss portion 3 protruding toward the outside of the vehicle body is provided on the plate surface of the upper section 2 of the D-pillar reinforcement plate, and the front side edge of the first boss portion 3 is arranged outside and behind the rear side window to form a reinforcement structure with a protruding arrangement. The first boss portion 3 is integrally formed on the upper section 2 of the D-pillar reinforcement plate, which is easy to process and reduces the difficulty of manufacturing the structure. The other edges of the first boss portion 3 are arranged along the edges of the upper section 2 of the D-pillar reinforcement plate, and the two edges are spaced a certain distance apart to ensure that each position of the upper section 2 of the D-pillar reinforcement plate can be effectively reinforced.

[0034] Furthermore, a second boss portion 4 that continues to protrude toward the outside of the vehicle body is provided on the first boss portion 3, and the outer peripheral edge of the second boss portion 4 is provided in a conformal manner with the outer edge of the first boss portion 3, and a certain distance is spaced between the two edges, so as to further strengthen the first boss portion 3. At the same time, the second boss portion 4 and the first boss portion 3 are provided in a configuration that can form a double-layer step structure, which has a more obvious and effective structural strengthening effect on the upper section 2 of the D-pillar reinforcement plate, improves the structural rigidity and structural strength of the upper section 2 of the D-pillar reinforcement plate, and at the same time strengthens the force transmission channel at the rear of the vehicle, improves the torsional rigidity and strength of the entire vehicle, and realizes effective strengthening of the D-pillar structure.

[0035] In some possible implementations, the second boss portion 4 described above is configured as follows: Figure 1 , Figures 3 to 5 See the structure shown. Figure 1 , Figures 3 to 5 The second boss portion 4 has two downwardly extending extension ends 41 below it, and the two extension ends 41 are spaced apart along the front-to-back direction. The two extension ends 41 are spaced apart along the front-to-back direction.

[0036] In this embodiment, the two extension ends 41 arranged below the second boss portion 4 effectively extend the extension length of the lower edge of the second boss portion 4 on the first boss portion 3, optimize the structure of the component, and form a structural reinforcement effect in the up and down directions. Without increasing the consumption of structural materials, the structural performance of the second boss portion 4 is improved, which helps to improve the torsional stiffness and strength of the entire vehicle.

[0037] Specifically, the two extension ends 41 are respectively disposed close to the front side edge and the rear side edge of the second boss portion 4 , which is convenient for mold making, conducive to structural molding, reduces the difficulty of mold making, and improves the manufacturing efficiency of components.

[0038] In some possible implementations, the first through hole 42 described above is formed as follows: Figure 1 , Figure 3 and Figure 4 See the structure shown. Figure 1 , Figure 3 and Figure 4A first through hole 42 is provided on the second boss portion 4. A plurality of first through holes 42 are provided on the second boss portion 4. The first through holes 42 are spaced apart in the up and down directions. A first reinforcing rib 43 is provided on the edge of each first through hole 42. The first reinforcing rib 43 is recessed on the second boss portion 4 toward the inner side of the vehicle body.

[0039] In the present embodiment, on the basis of ensuring the structural strength, a first through hole 42 is further provided on the second boss portion 4. The provision of the first through hole 42 can, on the one hand, effectively reduce the self-weight of the component and reduce the material consumption of the component. On the other hand, the provision of the first through hole 42 is also convenient for the operator to observe and facilitate the positioning, installation and alignment of the component. At the same time, the provision of the first through hole 42 is also convenient for the operator to extend his hand into the cavity formed by the side window inner panel 1 and the upper section 2 of the D-pillar reinforcement plate, so as to facilitate the installation and disassembly of the components installed in the cavity and improve the convenience of operation.

[0040] Two, three or other numbers of the first through holes 42 can be provided. Since the first boss portion 3 extends a certain length in the vertical direction, a plurality of first through holes 42 can be spaced apart in the vertical direction. The hole shape of the first through hole 42 can be set arbitrarily, or can be set along the edge of the second boss portion 4 in accordance with the shape, and on the basis of strengthening the structure of the second boss portion 4, the material consumption of the structure is reduced to achieve the effect of weight reduction, so as to meet the requirements of lightweight design.

[0041] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The area of ​​the second boss portion 4 is smaller than that of the first boss portion 3, and the height of the second boss portion 4 protruding from the first boss portion 3 is smaller than the height of the first boss portion 3 protruding from the upper section 2 of the D-pillar reinforcement plate. The second boss portion 4 is arranged on the first boss portion 3, and the second boss portion 4 is located within the range that can be covered by the first boss portion 3. Therefore, the area of ​​the second boss portion 4 should be smaller than that of the first boss portion 3, and the convex shape of the first boss portion 3 is matched to finally form a double-layer step shape, achieving a good structural reinforcement effect.

[0042] The protruding height of the first boss portion 3 is greater than that of the second boss portion 4 , which can provide a stable basis for the arrangement of the second boss portion 4 , thereby having a more reliable structural reinforcement effect than the second boss portion 4 .

[0043] In some possible implementations, the above-mentioned characteristic side window inner panel 1 is adopted as follows Figure 2 , Figure 3 and Figure 6 See the structure shown. Figure 2 , Figure 3 and Figure 6The side window inner panel 1 is provided with a third boss portion 5 which is protruded toward the center axis side of the vehicle body. The third boss portion 5 is arranged inside and outside corresponding to the first boss portion 3 . The third boss portion 5 extends in the up-down direction. A second through hole 51 is penetrated through the third boss portion 5 .

[0044] In this embodiment, the side window inner panel 1 is provided with a third boss portion 5 while meeting the molding requirements. The third boss portion 5 extends in the up-down direction, and its cross section can form a "J"-shaped gradient cross-section structure, which is convenient for structural reinforcement, improving the structural rigidity and strength of the component, and cooperating with the upper section 2 of the D-pillar reinforcement plate to effectively reinforce the D-pillar and improve the overall structural performance of the D-pillar.

[0045] On the basis of the above structure, the third boss portion 5 is arranged correspondingly to the first boss portion 3 inside and outside, so that the corresponding positions of the side window inner panel 1 and the upper section 2 of the D-pillar reinforcement plate in the inner and outer directions can be structurally reinforced, and the D-pillar area is structurally reinforced from both the inside and outside, which has a better structural reinforcement effect.

[0046] In some possible implementations, the third boss portion 5 is as follows: Figures 6 to 9 See the structure shown. Figures 6 to 9 The protruding height of the third boss portion 5 gradually increases from top to bottom, and a second reinforcing rib 52 is provided at the edge of the second through hole 51. The second reinforcing rib 52 is recessed toward the outer side of the vehicle body and arranged on the third boss portion 5.

[0047] In some embodiments, the second through hole 51 can be formed as follows: Figure 2 , Figure 3 and Figure 6 See the structure shown. Figure 2 , Figure 3 and Figure 6 A plurality of second through holes 51 are provided on the third boss portion 5 , and the second through holes 51 are arranged at intervals along the extending direction of the third boss portion 5 .

[0048] In the present embodiment, the third boss portion 5 is arranged to protrude toward the center axis side of the vehicle body relative to the inner side of the side window, and its protrusion height gradually changes. The protrusion size of the area located at the upper part of the third boss portion 5 is smaller, and the protrusion size of the area located at the lower part of the third boss portion 5 is larger, forming a trend that the protrusion size gradually increases from top to bottom, which has a certain gradual effect, further improving the structural reinforcement performance of the third boss portion 5.

[0049] The third boss portion 5 has a larger protrusion size in the lower area, and a smaller protrusion size in the upper area. The lower area of ​​the third boss portion 5 can provide good support for the upper area, further strengthening the structure of the side window inner panel 1.

[0050] In some embodiments, the second through hole 51 can be formed as follows: Figure 2 , Figure 3 and Figure 6 See the structure shown. Figure 2 , Figure 3 and Figure 6 The second through hole 51 is an oblong hole, and the long axis direction of the second through hole 51 is consistent with the extending direction of the third boss portion 5 .

[0051] In this embodiment, a plurality of second through holes 51 are arranged at intervals on the side window inner panel 1, and each second through hole 51 extends along the extension direction of the third boss portion 5. The second through holes 51 adopt the structural form of an oblong hole, and the two ends are semicircular holes, and are arranged at intervals along the extension direction, thereby realizing a reasonable arrangement of the second through holes 51. The arrangement of the second through holes 51 not only avoids affecting the structural strength of the side window inner panel 1, but also realizes a certain degree of weight reduction and reduces material consumption.

[0052] In some embodiments, the above-mentioned characteristic side window inner panel 1 can be adopted as follows Figure 1 , Figure 2 , Figure 4 and Figure 6 See the structure shown. Figure 1 , Figure 2 , Figure 4 and Figure 6 The side window inner panel 1 protrudes downward from the lower edge of the upper section 2 of the D-pillar reinforcement plate, and the third boss portion 5 extends downward to the lower edge of the side window inner panel 1 .

[0053] In this embodiment, the upper section 2 of the D-pillar reinforcement plate can cooperate with the lower section of the D-pillar reinforcement plate to form the entire D-pillar reinforcement plate, and the lower part of the side window inner panel 1 is connected to other components to form an inner panel structure. The side window inner panel 1 is arranged to protrude downward from the lower edge of the upper section 2 of the D-pillar reinforcement plate, so that the connecting seam between the side window inner panel 1 and the lower component and the connecting seam between the upper section 2 of the D-pillar reinforcement plate and the lower section of the D-pillar reinforcement plate can be staggered in the up and down directions to avoid the two forming corresponding effects in the inner and outer directions of the vehicle body, thereby avoiding structural attenuation at this position, facilitating the enhancement of the structural reinforcement effect of the side window inner panel 1 and the upper section 2 of the D-pillar reinforcement plate on the D-pillar, ensuring the structural performance of the D-pillar, effectively enhancing the rear force transmission channel, improving the torsional stiffness and structural strength of the whole vehicle, and ultimately improving the safety of the vehicle.

[0054] The above-mentioned D-pillar reinforcement structure is formed by enclosing the side window inner panel 1 and the upper section 2 of the D-pillar reinforcement plate. A double-layer step effect is formed by arranging a first boss portion 3 on the upper section 2 of the D-pillar reinforcement plate and arranging a second boss portion 4 on the first boss portion 3, which facilitates improving the structural rigidity and strength of the component. The area behind the rear side window close to the D-pillar is structurally reinforced, which can effectively strengthen the force transmission channel in the rear area of ​​the side beam, improve the torsional rigidity and structural strength of the entire vehicle, and thus improve the overall safety performance of the vehicle.

[0055] Based on the same inventive concept, the embodiment of the present application further provides a vehicle, which includes a D-pillar reinforcement structure. The vehicle forms a double-layer step effect by arranging a first boss portion 3 on the upper section 2 of the D-pillar reinforcement plate and a second boss portion 4 on the first boss portion 3, so as to facilitate structural reinforcement of the area near the D-pillar at the rear of the rear side window, effectively strengthen the force transmission channel in the rear area of ​​the side beam, and improve the torsional rigidity and structural strength of the whole vehicle, thereby improving the overall safety performance of the vehicle.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
