[0040] Reference below Figure 1-Figure 13 A vehicle body rear structure 10 according to an embodiment of the present invention will be described.

[0041] like Figure 1-Figure 13 As shown, the vehicle body rear structure 10 according to the embodiment of the utility model includes: a side panel assembly 1.

[0042] Specifically, refer to Figure 8-Figure 10 The side enclosure assembly 1 includes: a side enclosure outer panel 11, an inner rear wheel cover 12, an outer rear wheel cover 13 and a C-pillar 14. The front end of the outer rear wheel cover 13 is connected to the outer side of the C-pillar 14, and the front end of the inner rear wheel cover 12 is connected to the inner side of the C-pillar 14. It should be noted that the vehicle body rear structure 10 also includes a vehicle body frame and a chassis.

This not only increases the distance between the outer rear wheel cover 13 and the inner rear wheel cover 12 along the left-right direction of the vehicle, but also enables the C-pillar 14, the outer rear wheel cover 13 and the inner rear wheel cover 12 to work together to withstand torque, thereby improving the torsional stiffness of the rear structure 10 of the vehicle body, reducing the deformation of the door opening frame, and improving the dynamic stiffness of the chassis mounting point, thereby improving the riding comfort of users.

[0044] Furthermore, if Figure 8-Figure 10 As shown, the front end of the side outer panel 11 is connected to the outer side of the C-pillar 14, and the side outer panel 11 is located outside the outer rear wheel cover 13 and connected to the outer rear wheel cover 13. Therefore, the C-pillar 14, the side outer panel 11 and the outer rear wheel cover 13 can also bear the torque together, thereby further improving the torsional rigidity of the rear structure 10 of the vehicle body, thereby further reducing the deformation of the door opening frame, and improving the dynamic rigidity of the chassis mounting point, thereby improving the riding comfort of the user.

[0045] According to the vehicle body rear structure 10 of the embodiment of the utility model, the front end of the outer rear wheel cover 13 is connected to the outer side surface of the C-pillar 14, and the front end of the inner rear wheel cover 12 is connected to the inner side surface of the C-pillar 14. This not only increases the distance between the outer rear wheel cover 13 and the inner rear wheel cover 12 along the left-right direction of the vehicle, but also enables the C-pillar 14, the outer rear wheel cover 13 and the inner rear wheel cover 12 to work together to withstand torque, thereby improving the torsional stiffness of the vehicle body rear structure 10, reducing the deformation of the door opening frame, and improving the dynamic stiffness of the chassis mounting point, thereby improving the riding comfort of users.

[0046] In some embodiments of the present invention, Figure 1-Figure 3 and Figure 11-13 As shown, the rear vehicle body structure 10 also includes: a door sill 2, which is located at the lower end of the C-pillar 14 and connected to the C-pillar 14, a portion of the door sill 2 is located between the inner rear wheel cover 12 and the outer rear wheel cover 13 and connected to the outer rear wheel cover 13, and the door sill 2 is connected to the side outer panel 11.

The plurality of reinforcing ribs 21 divide the first cavity 22 into a plurality of spaced-apart sub-cavities 221, and each sub-cavity 221 penetrates the threshold 2 along its length direction.

[0049] It is understandable that the provision of the first cavity 22 can not only increase the cross-sectional area (cross-sectional area perpendicular to the length direction of the vehicle) of the door sill 2, increase the structural strength of the door sill 2, but also reduce the weight of the door sill 2. The plurality of reinforcing ribs 21 extend along the length direction of the vehicle, thereby further improving the structural strength of the door sill 2, thereby further improving the structural strength of the rear structure 10, thereby further improving the torsional rigidity of the rear structure 10, reducing the deformation of the door opening frame, and improving the dynamic rigidity of the chassis mounting point, thereby improving the riding comfort of the user.

[0051] It can be understood that the side sealing plate 32 is connected to the door sill 2 and the side panel assembly 1, the front connecting plate 33 is connected to the door sill 2 and the side panel assembly 1, and the front connecting plate 33, the side sealing plate 32 and the rear longitudinal beam body 31 are all connected, so that the rear longitudinal beam assembly 3 is connected to the door sill 2 and the side panel assembly 1, so that the rear longitudinal beam assembly 3, the door sill 2 and the side panel assembly 1 can jointly withstand torque and force, thereby further improving the structural strength of the rear vehicle body structure 10, thereby further improving the torsional stiffness of the rear vehicle body structure 10, reducing the deformation of the door opening frame, and improving the dynamic stiffness of the chassis mounting point, thereby improving the riding comfort of the user.

[0052] Furthermore, if Figure 1 , Figure 4-Figure 7 and Figure 11-13 As shown, the front connecting plate 33, the side sealing plate 32 and the front end of the rear longitudinal beam body 31 are all connected to the door sill 2, thereby further increasing the connection area between the rear longitudinal beam assembly 3 and the door sill 2, thereby improving the connection reliability between the rear longitudinal beam assembly 3 and the door sill 2. The side sealing plate 32 extends in the up-down direction, thereby simultaneously increasing the connection area between the side sealing plate 32 and the door sill 2 and the connection area between the side sealing plate 32 and the side enclosure assembly 1, and the front connecting plate 33 extends in the up-down direction, thereby simultaneously increasing the connection area between the front connecting plate 33 and the door sill 2 and the connection area between the front connecting plate 33 and the side enclosure assembly 1, thereby further improving the connection reliability between the rear longitudinal beam assembly 3 and the door sill 2 and the side enclosure assembly 1.

[0053] In some embodiments of the present invention, Figure 1 , Figure 4-Figure 7 and Figure 11-13As shown, the upper end of the front connecting plate 33 is connected to the inner side surface of the C-pillar 14, and the lower end of the front connecting plate 33 is connected to the door sill 2; it can be understood that the front connecting plate 33 is connected to both the C-pillar 14 and the door sill 2, so that a more reliable connection relationship is formed between the rear longitudinal beam assembly 3, the C-pillar 14 and the door sill 2, thereby improving the connection reliability between the C-pillar 14, the door sill 2 and the rear longitudinal beam assembly 3, so that the rear longitudinal beam assembly 3, the door sill 2 and the side panel assembly 1 can better withstand torque and force, thereby further improving the structural strength of the rear structure 10 of the vehicle body, thereby further improving the torsional stiffness of the rear structure 10 of the vehicle body, reducing the deformation of the door opening frame, and improving the dynamic stiffness of the chassis mounting point, thereby improving the riding comfort of the user.

[0054] Furthermore, if Figure 1 , Figure 4-Figure 7 and Figure 11-13 As shown, the upper end of the front connecting plate 33 is bent toward the inner side of the C-pillar 14 along the left-right direction of the vehicle, so as to facilitate the connection between the upper end of the front connecting plate 33 and the inner side of the C-pillar 14 .

[0055] In some embodiments of the present invention, Figure 1 , Figure 4-Figure 7 and Figure 11-13 As shown, along the up-down direction, the inner rear wheel cover 12 is arranged on the upper side of the rear longitudinal beam body 31, and the upper end of the side sealing plate 32 is connected to the inner rear wheel cover 12, and the lower end of the front connecting plate 33 is connected to the door sill 2; it can be understood that the side sealing plate 32 is connected to both the inner rear wheel cover 12 and the door sill 2, so that a more reliable connection relationship is formed between the rear longitudinal beam assembly 3, the inner rear wheel cover 12 and the door sill 2, thereby improving the connection reliability between the inner rear wheel cover 12, the door sill 2 and the rear longitudinal beam assembly 3, so that the rear longitudinal beam assembly 3, the door sill 2 and the side panel assembly 1 can better withstand torque and force, thereby further improving the structural strength of the rear structure 10 of the vehicle body, thereby further improving the torsional stiffness of the rear structure 10 of the vehicle body, reducing the deformation of the door opening frame, and improving the dynamic stiffness of the chassis mounting point, thereby improving the riding comfort of the user.

[0056] In some embodiments of the present invention, the side sealing plate 32 and the front connecting plate 33 are separate processed parts and connected. It can be understood that since the upper ends of the side sealing plate 32 and the front connecting plate 33 are respectively connected to the inner side of the inner rear wheel cover 12 and the C-pillar 14, the side sealing plate 32 and the front connecting plate 33 are separate processed parts, so that it is convenient for the side sealing plate 32 and the front connecting plate 33 to be made into different shapes to better adapt to the inner rear wheel cover 12 and the C-pillar 14, so that it is more convenient for the side sealing plate 32 to be connected to the inner rear wheel cover 12, and the front connecting plate 33 to be connected to the C-pillar 14.

[0057] In some embodiments of the present invention, Figure 1 and Figure 11-13 As shown, the rear longitudinal beam assembly 3 and the side panel assembly 1 are connected to the door sill 2 by at least one of FDS (Flow Drill Screw), SPR (Self-piercing rivets) and fasteners; thereby, the connection reliability between the rear longitudinal beam assembly 3 and the side panel assembly 1 and the door sill 2 is improved. For example, in the present invention, the rear longitudinal beam assembly 3 and the side panel assembly 1 are connected to the door sill 2 by FDS, SPR and fasteners.

[0058] In some embodiments of the present invention, Figure 1 and Figure 11-13 As shown, the side panel assembly 1 is connected to the rear longitudinal beam assembly 3 by steel spot welding and welding, thereby further improving the connection reliability between the side panel assembly 1 and the rear longitudinal beam assembly 3.

[0059] In some embodiments of the present invention, the rear body structure 10 is made of aluminum alloy. It is understandable that aluminum alloy is lighter than other metal materials, so the weight of the rear body structure 10 can be reduced, thereby reducing the overall weight of the vehicle, thereby achieving the effect of improving vehicle endurance and reducing vehicle energy consumption.

[0060] In some embodiments of the present invention, the C-pillar 14 includes: a C-pillar outer panel 141 and a C-pillar inner panel 142, the C-pillar outer panel 141 is located on the outside of and connected to the C-pillar inner panel 142, a second cavity 143 is defined between the C-pillar outer panel 141 and the C-pillar inner panel 142, the front end of the outer rear wheel cover 13 is connected to the C-pillar outer panel 141, the front end of the inner rear wheel cover 12 is connected to the C-pillar inner panel 142, and the front end of the side outer panel 11 is connected to the C-pillar outer panel 141.

[0061] It can be understood that the second cavity 143 is defined between the C-pillar outer panel 141 and the C-pillar inner panel 142, thereby increasing the cross-sectional size of the C-pillar 14 along the left-right direction of the vehicle, thereby improving the rigidity of the C-pillar 14, and also further increasing the distance between the outer rear wheel cover 13 and the inner rear wheel cover 12 along the left-right direction of the vehicle, thereby further improving the torsional rigidity of the rear body structure 10, reducing the deformation of the door opening frame, and improving the dynamic rigidity of the chassis mounting point, thereby improving the riding comfort of the user.
