[0042] In this embodiment, a reinforcing beam 6 is also included, and the reinforcing beam 6 includes:
[0043] A cross beam 64, which is disposed on the rear floor 1 and is spaced apart from the rear side wall 7 near the front of the vehicle;
[0044] The two vertical beams, the cross beam 64 and the two vertical beams are in a "J"-shaped structure, one end of the vertical beam is connected to the cross beam 64, and the other end of the vertical beam is extended to the rear side wall 7 through the rear longitudinal beam 2 and the rear wheel cover.
[0045] Specifically, the position stability among the rear wheel housing, the rear longitudinal beam 2 and the rear panel is improved by the reinforcement beam 6 .
[0046] In this embodiment, the vertical beam includes:
[0047] A lower reinforcing plate 63, which is L-shaped, with one end of the lower reinforcing plate 63 connected to the crossbeam 64 and the rear floor 1, and the other end of the lower reinforcing plate 63 connected to the rear longitudinal beam 2 and the connecting plate 4;
[0048] A middle reinforcing plate 62, which is disposed on the connecting plate 4, and one end of the middle reinforcing plate 62 is connected to the other end of the lower reinforcing plate 63;
[0049] The upper reinforcing plate 61 has one end connected to the other end of the middle reinforcing plate 62 , and the other end of the upper reinforcing plate 61 is connected to the rear side panel 7 .
[0050] Specifically, the segmented arrangement of the vertical beam facilitates the processing and assembly of complex surfaces inside the vehicle.
[0051] In this embodiment, the upper reinforcing beam 6 is arranged obliquely.
[0052] Specifically, the upper reinforcing beam 6 obliquely arranged can serve as a diagonal rib to support the rear wheel housing and the rear side panel 7 .
[0053] In this embodiment, the upper reinforcing plate 61 or the middle reinforcing plate 62 is provided with an installation avoidance hole 621 for the rear shock absorber.
[0054] Specifically, the avoidance hole 621 is installed to facilitate installation of the fixing bolts of the rear shock absorber.
[0055] In this embodiment, the cross section of the reinforcing beam 6 is C-shaped or annular, and the opening side of the reinforcing beam 6 with the C-shaped cross section is connected and closed to the rear floor 1 and the rear wheel cover.
[0056] Specifically, the hollow reinforcement beam 6 ensures the strength of the rear vehicle body while reducing the weight.
[0057] The utility model also provides an automobile, comprising the above automobile body rear structure.
[0058] Specifically, by utilizing the above-mentioned rear structure of the automobile body, the installation and adjustment space of the rear seats can be increased without increasing the length of the vehicle and the wheelbase of the front and rear axles.
[0059] In this embodiment, when a car having the rear structure of the car body is used, the assembly is used as an example:
[0060] In order to assemble the long slide rail, it is necessary to increase the X-direction space of the second row. This solution adopts the technical solution of obliquely installing the rear shock absorber 8, such as Figure 2 As shown. The rear wheel cover assembly is divided into two parts, namely the cover body 3 and the connecting plate 4. The connecting plate 4 is arranged at the rear of the cover body 3 through the transition portion 5, and together they constitute the mounting structure of the rear shock absorber. The rear shock absorber is installed on the aforementioned mounting structure at a rearward tilt. The advantage of this design is that the mounting point of the rear shock absorber can be closer to the rear of the vehicle compared to the traditional design, thereby increasing the X-direction space of the rear row, ensuring that the long slide rails of the seat can be installed without increasing the wheelbase. In addition, the inclined shock absorber mounting structure can provide design space for designing a more comfortable backrest angle for the second row of seats, thereby improving the riding comfort of the second row.
[0061] The rear floor 1 is designed as a flat structure. Figure 1 As shown, the installation convenience of the long slide rail can be increased. Under the condition of meeting the performance requirements, the Y-direction width of the cover body 3 should be as small as possible to increase the Y-direction interior space of the second row, thereby providing design space for increasing the width of the second row sliding seats, thereby improving the riding comfort of the second row.
[0062] The present invention also designs a reinforcing beam 6 at the rear of the vehicle body to improve the overall rigidity of the vehicle body and the strength of the rear shock absorber mounting point. The reinforcing beam 6 includes an upper reinforcing plate 61, a middle reinforcing plate 62, a lower reinforcing plate 63 and a cross beam 64, and the cross sections are all in a "J" shape, such as Figure 3 shown.
[0063] The upper reinforcing plate 61 is connected to the connecting plate 4 by welding, one end of the upper reinforcing plate 61 is connected to the middle reinforcing plate 62 by welding points and bolts, and the other end is connected to the lower reinforcing plate 63 by welding points and plug welding, as shown in FIG. Figure 3 shown.
[0064] The other end of the middle reinforcing plate 62 is connected to the rear side panel 7 by bolts and welding points, and a shock absorber bolt installation avoidance hole 621 is arranged on the middle reinforcing plate 62. Figure 3 shown.
[0065] The other end of the lower reinforcing plate 63 is connected to the rear floor 1 and the cross beam 64 , and is also connected to the rear longitudinal beam 2 by plug welding in order to increase the strength of the connection.
[0066] The middle portion of the rear floor cross beam 64 is connected to the rear floor 1 via a welding point.
[0067] The structural parts in the reinforcing beam 6 are interconnected to form an annular reinforcement structure, which is connected to the rear floor 1, the connecting plate 4, the rear longitudinal beam 2 and the rear side panel 7 to form a closed C-ring structure, which can effectively improve the torsional stiffness of the entire vehicle and the installation point strength of the shock absorber, thereby ensuring the achievement of structural performance.
[0068] The X direction is along the front and rear direction of the car, the Y direction is along the left and right direction of the car, and the Z direction is along the up and down direction of the car.
[0069] The various embodiments of the utility model have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments.
