[0004] Rear floor: An important component of the passenger compartment, located at the rear of the vehicle body. It is generally equipped with rear seats and has a trunk pit; it connects downwards to the rear frame and rear shock absorbers, and transmits force and torque; its front, rear, and left and right sides are welded to the front floor, rear bulkhead, and side panels, respectively.

[0005] The existing skateboard chassis rear frame and rear floor are difficult to assemble, hindering the overall vehicle assembly. Therefore, a new decoupling structure between the skateboard chassis rear frame and rear floor is needed to facilitate vehicle assembly. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of the existing technology by providing a decoupling structure between the rear suspension frame and the rear floor of a skateboard chassis, thereby solving the problem that the existing skateboard chassis rear frame and rear floor are difficult to assemble and install, which is not conducive to the overall vehicle assembly.

[0039] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0040] like Figure 1-9 As shown, a decoupling structure between the rear suspension frame and the rear floor of a skateboard chassis includes:

[0041] Rear floor 1, the rear floor 1 is H-shaped, with the openings gradually widening and facing the front and rear of the vehicle respectively;

[0042] The rear frame 2 is set at the lower end of the rear floor 1 according to the shape. The rear frame 2 includes two cross beams and two longitudinal beams.

[0043] The two longitudinal beams are left longitudinal beam 23 and right longitudinal beam 24. The middle of the left longitudinal beam 23 and the right longitudinal beam 24 are close to each other and the two ends are far apart. Multiple assembly connection points for connecting to the rear floor 1 are provided on the left longitudinal beam 23 and the right longitudinal beam 24, respectively.

[0044] The two crossbeams are the front crossbeam 21 and the rear crossbeam 22, which are spaced apart between the left longitudinal beam 23 and the right longitudinal beam 24.

[0045] Specifically, the rear frame 2 and the rear floor 1 are stacked one on top of the other, which facilitates assembly and bolt fixing from top to bottom. The floor panel 11 is completely divided into the rear floor 1 of the upper vehicle body. The rear frame 2 has no panel structure, only a longitudinal and transverse beam structure. At the same time, the longitudinal beams of the rear frame 2 have an arched curved structure, with the front and rear ends facing outwards, which can maximize the lateral space for the front passenger compartment and significantly increase the width of the rear cargo tray, thereby maximizing the interior space of the vehicle. The rear frame 2 is set with two transverse beams dividing it into three parts, which provides a large space for the energy compartment of the front middle frame and also provides a certain strength for the rear frame 2 as a whole.

[0046] Furthermore, the assembly connection point is a decoupling connection point, used for the fixed connection of connecting components; in this design, it is a bolt connection point. The left longitudinal beam 23 and the right longitudinal beam 24 are respectively bow-shaped or C-shaped, with their openings facing opposite directions. The two crossbeams divide the left longitudinal beam 23 and the right longitudinal beam 24 into three equal parts. The rear crossbeam 22 is located close to the coil spring and shock absorber support structure of the rear suspension, providing sufficient strength for the torsional stiffness of the entire vehicle.

[0047] In this embodiment, the rear floor 1 includes two transverse floor beams and two longitudinal floor beams, with a floor panel 11 disposed between the two transverse floor beams, and a spare tire tray 12 disposed on the side of the rear floor 1 near the rear of the vehicle.

[0048] Specifically, the rear floor 1 panel is completely divided into the upper body rear floor 1, while the rear frame 2 has no panel structure.

[0049] In this embodiment, the rear frame 2 is provided with a nut or threaded sleeve that mates with the assembly connection point.

[0050] Specifically, the bolts pass through the assembly connection point from top to bottom and connect to the nut or threaded sleeve, ensuring that the bolts are all aligned and pointing downwards. This allows for more flexible assembly of the rear frame 2, which can be assembled with the suspension first and then connected to the rear body; or the rear frame 2 can be assembled with the rear body first and then with the rear suspension module. This assembly structure is adaptable to various assembly methods and processes, and can effectively adapt to both monocoque and non-monocoque production lines, significantly reducing production input.

[0051] In this embodiment, the rear crossbeam 22 is connected to the rear floor beam near the rear of the vehicle, and the front crossbeam 21 is connected to the ground panel 11 near the front of the vehicle.

[0052] In this embodiment, the rear floor 1 is provided with a first reinforcing plate 13, which is used to reinforce the connection between the transverse floor beam and the longitudinal floor beam.

[0053] In this embodiment, the first reinforcing plate 13 covers the connection between the transverse floor beam and the longitudinal floor beam, and both ends are fixed by assembly connection points.

[0054] Specifically, multiple assembly connection points are set on the longitudinal beam, and the first reinforcing plate 13 is installed and fixed by using two of them.

[0055] Furthermore, nine assembly connection points are provided, with the first reinforcing plate 13 utilizing the fifth and sixth points from left to right.

[0056] In this embodiment, a second reinforcing plate 3 is also included. The second reinforcing plate 3 is disposed on the upper side of the coil spring position and is used to reinforce the connection between the rear frame 2 and the rear floor 1.

[0057] Specifically, the second reinforcing plate 3 connects the rear frame 2 and the rear floor 1, greatly enhancing the decoupling strength. This position also contributes significantly to the installation strength of the shock absorber and coil spring.

[0058] In this embodiment, the crossbeams and longitudinal beams are tubular cavity structures.

[0059] Specifically, the tubular cavity structure improves support stability. The same structure can also be used for the transverse floor beams and the two longitudinal floor beams.

[0060] In this embodiment, bolts are inserted through the assembly connection points from top to bottom, and the bolts are not exposed outside the cavity structure.

[0061] Specifically, the threaded ends of the bolts are concealed, which is both aesthetically pleasing and avoids external interference.

[0062] This utility model also provides an automobile, including the above-mentioned skateboard chassis rear suspension rear frame and rear floor decoupling structure.

[0063] In this embodiment, a decoupling structure for the rear suspension, rear frame, and rear floor of a skateboard chassis is used, taking installation as an example:

[0064] The rear frame 2 is equipped with threaded sleeves or nuts, and bolts pass through the rear body from top to bottom to connect with the rear frame 2. The bolts are installed uniformly from top to bottom, which makes the assembly of the rear frame 2 more flexible. It can be assembled with the suspension first and then connected to the rear body; or the rear frame 2 can be assembled with the rear body first and then assembled with the rear suspension module. This assembly structure is adaptable to a variety of assembly methods and processes, and can effectively adapt to both monocoque and non-monocoque body production lines, greatly reducing production input.

[0065] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
