[0040] Embodiment one

[0041] The embodiment relates to a vehicle body side structure, which can strengthen the structural strength and force transmission performance between CD pillars, and improve the structural strength and force transmission performance of the rear side of the vehicle.

[0042] As shown in the overall structure, Figure 1 The vehicle body side structure of the embodiment comprises a C pillar 1, a D pillar 2, a roof upper side beam 3, a CD pillar connecting cross beam 4 and a CD pillar reinforcing cross beam 5. Among them, the C pillar 1, the D pillar 2, the roof upper side beam 3 and the CD pillar connecting cross beam 4 are surrounded to form a window area. And the CD pillar reinforcing cross beam 5 is located in the window area, and the two ends of the CD pillar reinforcing cross beam 5 are connected with the C pillar 1 and the D pillar 2 respectively.

[0043] At this time, in the above structure, the C pillar 1, the D pillar 2, the roof upper side beam 3 and the CD pillar connecting cross beam 4 are surrounded to form a window area, and the CD pillar reinforcing cross beam 5 with two ends connected with the C pillar 1 and the D pillar respectively is arranged in the window area. This not only can better strengthen the structure between the C pillar 1 and the D pillar 2, but also the collision force transmitted to the C pillar 1 and the D pillar 2 can be transmitted through the CD pillar reinforcing cross beam 5, which is beneficial to improve the force transmission performance of the window area, thereby improving the structural strength and force transmission performance of the rear side of the vehicle, so as to improve the impact resistance of the rear side of the vehicle and improve the safety performance of the vehicle.

[0044] Among them, it needs to explain that for the vehicle type with C pillar 1 and D pillar 2, the left and right sides of the vehicle body are provided with the vehicle body side structure of the embodiment, and the structures of the two sides are the same. In the following, one side will be taken as an example to introduce the structure in detail.

[0045] In detail, continue to refer to Figure 1 In the embodiment, the roof upper side beam 3 comprises an upper side beam main body and an upper side beam rear section connected to the rear end of the upper side beam main body. The upper side beam rear section is arc-shaped, and gradually inclines downward from front to rear along the front-rear direction of the whole vehicle. The upper side beam rear section specifically surrounds the C pillar 1, the D pillar 2 and the CD pillar connecting cross beam 4 to form the above-mentioned window area.

[0046] Referring to Figure 1 and Figure 2 As shown in Figs. 1 and 2, as a preferred embodiment, the side structure of the vehicle body of the present embodiment further comprises a side window inner panel 6 arranged inside the window region, the periphery of the side window inner panel 6 is connected with the C-pillar 1, the D-pillar 2, the roof upper side beam 3 and the CD-pillar connecting cross beam 4 respectively, and the side window inner panel 6 is provided with a glass mounting port 601.

[0047] The CD-pillar reinforcing cross beam 5 comprises a window upper cross beam 501 and a window lower cross beam 502 connected between the C-pillar 1 and the D-pillar 2, and the window upper cross beam 501 and the window lower cross beam 502 are arranged near the upper and lower sides of the glass mounting port 601 respectively.

[0048] In the specific implementation, the periphery of the side window inner panel 6 is welded to the C-pillar 1, the D-pillar 2, the roof upper side beam 3 and the CD-pillar connecting cross beam 4 respectively. The window upper cross beam 501 and the window lower cross beam 502 are both welded to the outer side of the side window inner panel 6.

[0049] In the present embodiment, the CD-pillar reinforcing cross beam 5 comprises the window upper cross beam 501 and the window lower cross beam 502, so that two transverse force transmission channels are formed between the C-pillar 1 and the D-pillar 2, which further improves the structural strength of the window region and the force transmission performance between the C-pillar 1 and the D-pillar 2. The window upper cross beam 501 and the window lower cross beam 502 are arranged near the upper and lower sides of the glass mounting port 601 respectively, which is conducive to uniform force transmission between the C-pillar 1 and the D-pillar 2, thereby further improving the safety performance of the vehicle.

[0050] As a further preferred embodiment, in the present embodiment, the connection position M of the window upper cross beam 501 to the C-pillar 1 is higher than the connection position N of the window upper cross beam 501 to the D-pillar 2. In this way, uniform force transmission between the C-pillar 1 and the D-pillar 2 is facilitated.

[0051] In terms of specific structure, as a preferred embodiment, as shown in the perspective view of Fig. 3, the window upper cross beam 501 of the present embodiment is roughly S-shaped in a zigzag manner, one end of the window upper cross beam 501 is welded to the C-pillar 1, and the other end of the window upper cross beam 501 is welded to the D-pillar 2. Figure 1 and Figure 2 In terms of specific structure, as a preferred embodiment, as shown in the perspective view of Fig. 3, the window upper cross beam 501 of the present embodiment is roughly S-shaped in a zigzag manner, one end of the window upper cross beam 501 is welded to the C-pillar 1, and the other end of the window upper cross beam 501 is welded to the D-pillar 2. Figure 1 and Figure 2 In terms of specific structure, as a preferred embodiment, as shown in the perspective view of Fig. 3, the window upper cross beam 501 of the present embodiment is roughly S-shaped in a zigzag manner, one end of the window upper cross beam 501 is welded to the C-pillar 1, and the other end of the window upper cross beam 501 is welded to the D-pillar 2.

[0052] Furthermore, in this embodiment, the upper horizontal beam 501 of the window has a Z-shaped cross-section and connecting flanges on both sides. In specific implementation, the upper horizontal beam 501 of the window is welded to the outer side of the inner panel of the side window through the connecting flanges on both sides. In terms of specific structure, the upper horizontal beam 501 of the window specifically includes a front section 5011, a middle connecting section 5012, and a rear section 5013 of the upper horizontal beam connected sequentially from front to back.

[0053] Among them, the front section 5011, the middle connecting section 5012, and the rear section 5013 of the upper crossbeam all gradually slope downward from front to back along the front-rear direction of the whole vehicle. The inclination angle of the middle connecting section 5012 is greater than that of the front section 5011, and the inclination angle of the middle connecting section 5012 is greater than that of the rear section 5013. The front section 5011, the middle connecting section 5012, and the rear section 5013 of the upper crossbeam form a continuous curved structure to facilitate the balance between structural strength and force transmission performance.

[0054] It should be noted that the inclination angle of the front section 5011 of the upper crossbeam specifically refers to the angle between the front section 5011 of the upper crossbeam and the horizontal plane. The inclination angle of the middle connecting section 5012 of the upper crossbeam specifically refers to the angle between the middle connecting section 5012 of the upper crossbeam and the horizontal plane. The inclination angle of the rear section 5013 of the upper crossbeam specifically refers to the angle between the rear section 5013 of the upper crossbeam and the horizontal plane.

[0055] In specific implementation, the front end of the upper crossbeam front section 5011 is connected to the C-pillar 1, and the rear end of the upper crossbeam rear section 5013 is connected to the D-pillar. At this time, the upper crossbeam front section 5011, the upper crossbeam middle connecting section 5012, and the upper crossbeam rear section 5013 are all set to gradually slope downward from front to back along the front-rear direction of the whole vehicle, and are connected by the upper crossbeam middle connecting section 5012. On the one hand, this facilitates the uniform arrangement of the lateral force transmission structure, and on the other hand, it facilitates the mutual force transmission between the C-pillar 1 and the D-pillar.

[0056] Based on the structural arrangement of the upper crossbeam 501 of the window, and also as a preferred embodiment, in this embodiment, the lower crossbeam 502 of the window gradually slopes downward from front to back along the longitudinal direction of the entire vehicle. This facilitates the uniform arrangement of the lateral force transmission structure and also facilitates the mutual force transmission between the C-pillar 1 and the D-pillar 2.

[0057] Considering that column C1 is an important force-transmitting component between the top beam 3 and the connecting beam 4 of columns CD, in this embodiment, preferably, it is combined with... Figure 1 , Figure 3 to Figure 5 As shown, in this embodiment, column C1 gradually tilts forward from bottom to top.

[0058] In this way, the C pillar 1 can be used to transmit force between the roof upper side beam 3 and the CD pillar connecting cross beam 4, thereby further improving the crashworthiness of the rear side of the vehicle. In this embodiment, the D pillar 2 is arranged vertically. In this way, the structure of the D pillar 2 is facilitated, and the D pillar 2 can also be used to transmit force between the roof upper side beam 3 and the CD pillar connecting cross beam 4.

[0059] In this embodiment, as a preferred implementation form, the CD pillar connecting cross beam 4 extends in the front-rear direction of the vehicle, and the CD pillar connecting cross beam 4 has an extension section 401 extending from the D pillar 2 to the rear of the vehicle. At this time, arranging the CD pillar connecting cross beam 4 to extend in the front-rear direction of the vehicle can further facilitate force transmission between the C pillar 1 and the D pillar 2, and the use of the extension section 401 allows the impact force on the C pillar 1 and the D pillar 2 to continue to be transmitted from the D pillar to the rear, thereby improving the force transmission performance of the CD pillar connecting cross beam 4.

[0060] Continuing to refer to Figure 1 , Figure 3 to Figure 5 The body side structure of this embodiment also includes a rear shock absorber mounting bracket 7, the upper portion of which is connected to the CD pillar connecting cross beam 4. At this time, the force received by the rear shock absorber mounting bracket 7 can be transmitted to the CD pillar connecting cross beam 4, and can be transmitted to the C pillar 1 and the D pillar 2 through the CD pillar connecting cross beam 4, and then to the roof upper side beam 3, so that the two longitudinal force transmission channels of the C pillar 1 and the D pillar 2 can transmit the force on the rear shock absorber mounting bracket 7, thereby improving the safety performance of the vehicle.

[0061] In specific implementation, the upper portion of the rear shock absorber mounting bracket 7 is connected to the outer side of the CD pillar connecting cross beam 4, and the lower portion of the rear shock absorber mounting bracket 7 is connected to the rear wheel cover plate. The rear shock absorber mounting bracket 7 can transmit various forces such as impact force, braking force and driving force from the road to the shock absorber, so that the shock absorber can respond in time according to the driving state of the vehicle and the road conditions, and buffer and absorb these forces through its compression and stretching, thereby reducing the impact on other parts of the vehicle. Moreover, the rear shock absorber mounting bracket 7 can also be used to transmit force to the C pillar 1.

[0062] In some possible implementations, as a preference, in this embodiment, at least one of the C pillar 1, the D pillar 2, the roof upper side beam 3, the CD pillar connecting cross beam 4 and the CD pillar reinforcing cross beam 5 is made of extruded aluminum. In this way, the processing of each component is facilitated, the weight is lighter, which is conducive to the lightweight design of the vehicle, and the structural strength of the rear side of the vehicle is also improved.

[0063] In specific implementation, the C-pillar 1, D-pillar 2, top cover upper beam 3, CD-pillar connecting beam 4, and CD-pillar reinforcing beam 5 of this embodiment are preferably made of extruded aluminum. Furthermore, during manufacturing, the thickness of the C-pillar 1 can be set, for example, between 2.5mm and 3.5mm, such as 2.5mm, 3mm, or 3.5mm; the thickness of the D-pillar can be set, for example, between 1.5mm and 2.5mm, such as 1.5mm, 2mm, or 2.5mm; the thickness of the top cover upper beam 3 can be set, for example, between 4mm and 6mm, such as 4mm, 5mm, or 6mm; and the thickness of the CD-pillar connecting beam 4 can be set, for example, between 2.5mm and 3.5mm, such as 2.5mm, 3mm, or 3.5mm.

[0064] The CD pillar reinforcing beams 5, namely the upper window beam 501 and the lower window beam 502, have a thickness of, for example, between 2.5mm and 3.5mm, such as 2.5mm, 3mm, or 3.5mm. Similarly, the thickness of the lower window beam 502 can be set between 2mm and 3mm, such as 2mm, 2.5mm, or 3mm. Based on this, the rear shock absorber mounting bracket 7 in this embodiment is preferably made of die-cast aluminum plate with a thickness between 2mm and 3mm, such as 2.5mm, 3mm, or 3.5mm.

[0065] At this point, by setting the material and thickness of each component as described above, we can not only meet the requirements for weight reduction, but also improve the structural strength performance, enhance the bending strength of the CD pillar, and eliminate the stress concentration problem in the inherent bending area of ​​the CD pillar.

[0066] In addition, in this embodiment, the CD pillar connecting beam 4 extends along the front-rear direction of the vehicle, the D pillar is arranged vertically, and the upper window beam 501 and the lower window beam 502 are arranged at intervals in the window area along the height direction of the vehicle.

[0067] And in terms of specific structural layout, such as Figure 3 As shown, the distance H1 between the front section 5011 of the upper horizontal beam 501 and the lower horizontal beam 502 of the window is less than 400mm, and can be set to, for example, 300mm, 320mm, 365mm, etc. The distance H2 between the rear section 5013 of the upper horizontal beam 501 and the lower horizontal beam 502 of the window is less than 200mm, and can be set to, for example, 145mm, 160mm, 180mm, etc.

[0068] The length H3 of the window lower cross beam 502 is set between 330 mm and 360 mm, for example, 330 mm, 343 mm, 360 mm, etc. The distance H4 between the window lower cross beam 502 and the CD column connecting cross beam 4 is set between 100 mm and 150 mm, for example, 100 mm, 101 mm, 130 mm, 150 mm, etc. The distance H5 between the CD column connecting cross beam 4 and the shock absorber mounting point is set between 140 mm and 150 mm, for example, 140 mm, 145 mm, 150 mm, etc. At this time, through the size design as above, not only the structural strength and the force transmission performance can be ensured, but also the number of parts can be reduced.

[0069] In addition, as shown in the drawings, Figure 4 In the embodiment, the included angle a1 between the upper cross beam front section 5011 and the upper cross beam middle connecting section 5012 is set between 130° and 140°, for example, 130°, 134°, 140°, etc., the included angle a2 between the upper cross beam middle connecting section 5012 and the upper cross beam rear section 5013 is set between 135° and 145°, for example, 135°, 142°, 145°, etc., the included angle a3 between the upper cross beam front section 5011 and the C column 1 is set between 75° and 85°, for example, 75°, 82°, 85°, etc., and the included angle a4 between the upper cross beam rear section 5013 and the D column is set between 80° and 90°, for example, 80°, 84°, 90°, etc.

[0071] In addition, in the embodiment, as shown in the drawings, Figure 5As shown, the force transmitted to the shock absorber mounting bracket 7 can be transmitted to the roof upper side beam 3 through the CD column connecting beam 4 along the C column 1 and the D column and the side window inner panel 6 respectively, and the force acting on the C column 1, the D column and the side window inner panel 6 can also be dispersed by the two force transmission channels formed by the window upper beam 501 and the window lower beam 502, so as to improve the force transmission performance of the rear side of the vehicle body and effectively improve the collision safety performance.
