[0058] This embodiment relates to a powertrain installation structure, combined with Figures 1 to 3 As shown in , the overall structure includes a first mounting bracket 7 and a second mounting bracket 202 arranged in the rear cabin of the vehicle. Among them, a first crossbeam 3 is arranged between the rear shock towers 1 on both sides of the rear cabin of the vehicle, and the first mounting bracket 7 is arranged on the first crossbeam 3. At the same time, the rear cabin lower longitudinal beam assemblies are respectively connected between the rear shock towers 1 on both sides and the vehicle cabin, and the second mounting brackets 202 are respectively arranged on the rear cabin lower longitudinal beam assemblies on both sides. Moreover, the connecting line between the second mounting brackets 202 on both sides and the first mounting bracket 7 is a triangle.

[0059] In this embodiment, the first mounting bracket 7 is arranged on the first crossbeam 3 between the rear shock towers 1 on both sides, and the second mounting brackets 202 are respectively arranged on the lower longitudinal beam assemblies of the rear cabin on both sides. Moreover, the connection lines between the second mounting brackets 202 on both sides and the first mounting brackets 7 are in a triangle shape, which can realize the installation arrangement of the power assembly in the rear cabin of the vehicle, and can also use the characteristics of the high strength of the triangular structure to ensure the stability of the power assembly installation, which helps to improve the quality of the whole vehicle.

[0060] Among them, as a preferred embodiment, Figure 4 As shown in , the first cross beam 3 of this embodiment has an end portion 302 connected to each side rear shock tower 1, and a middle portion 301 located between the end portions 302 on both sides. The first mounting bracket 7 is provided on the middle portion 301, and the outline of each end portion 302 projected in the left-right direction of the whole vehicle is larger than the outline of the middle portion 301 projected in the left-right direction of the whole vehicle. In this embodiment, by making the projection outline of the end portion 302 of the first cross beam 3 larger than the projection outline of the middle portion 301, the larger cross-sectional size of the end portion of the first cross beam 3 can be utilized to increase the stability of the connection with the rear shock tower 1.

[0061] like Figure 4As shown in , in order to further improve the lateral support effect of the first cross beam 3, a plurality of cavities arranged at intervals are formed on the end portion 302, and correspondingly, a cavity connected to some of the cavities is provided on the middle portion 301. Such an arrangement can also make the first cross beam 3 have a higher structural strength and better connection reliability with the rear shock tower 1.

The rear end of the first cross beam 3 is embedded in the slot 702 and is welded to the first mounting bracket 7, and the powertrain suspension can be connected to the two connecting ears 701 by bolts. It should be noted that the structure of the first mounting bracket 7 is not limited to Fig. 9 The structure shown in , which can be adjusted accordingly according to design requirements. In addition, in addition to the middle portion 301 and the end portion 302 having different profiles as described above, the first cross beam 3 can also be set to have the same cross section at each portion.

[0063] In addition, as a feasible implementation, both rear shock towers 1 are provided with connection grooves 106, and the ends of the first cross beam 3 are embedded in the connection grooves 106. By providing the connection grooves 106 on the rear shock towers 1, the ends of the first cross beam 3 are embedded in the connection grooves 106, which can increase the reliability of the connection between the first cross beam 3 and the rear shock towers 1 on both sides. It should be noted that in addition to providing the connection grooves 106 on the rear shock towers 1, it is also feasible not to provide the connection grooves 106, and it is also feasible to connect the ends of the first cross beam 3 to the inner side surfaces of the rear shock towers 1.

[0064] like Figure 1 and Figure 2 As shown in , as a preferred embodiment, the rear cabin lower longitudinal beam assembly on each side of this embodiment includes a rear cabin lower longitudinal beam 2 connected to the vehicle cabin, and a connecting beam 6 connected between the rear cabin lower longitudinal beam 2 and the rear shock tower 1, and the second mounting bracket 202 on each side is arranged on the rear cabin lower longitudinal beam 2 on the same side. The rear cabin lower longitudinal beam assembly of this embodiment includes the rear cabin lower longitudinal beam 2 and the connecting beam 6, which can facilitate the preparation of the rear cabin lower longitudinal beam assembly and the arrangement of the second mounting bracket 202.

[0065] Among them, Figure 7 and Figure 8As shown in , as a preferred embodiment, the rear cabin lower longitudinal beam 2 of this embodiment is cast, and the second mounting bracket 202 is integrally formed on the rear cabin lower longitudinal beam 2. In this way, the feature of easy processing by casting can be utilized to facilitate the preparation of the rear cabin lower longitudinal beam 2, and the reliability of the setting of the second mounting bracket 202 can also be ensured. Of course, in addition to integrally casting the rear cabin lower longitudinal beam 2 and the second mounting bracket 202, the two can also be separately set and made by other conventional methods such as machining technology.

[0066] In addition, continue to refer to Figure 7 and Figure 8 As shown in , in order to achieve a better use effect, a slot body with a notch facing the outside of the vehicle is formed on the lower longitudinal beam 2 of the rear cabin, and the slot body extends along the length direction of the lower longitudinal beam 2 of the rear cabin. In addition, in order to improve the structural strength of the lower longitudinal beam 2 of the rear cabin, a plurality of staggered ribs are provided in the slot body, and each rib body is supported between the upper and lower side walls of the slot body, so as to improve the strength of the lower longitudinal beam 2 of the rear cabin in the vertical direction of the whole vehicle. In addition, in order to improve the connection effect with the connecting beam 6, a convex portion is provided at the rear end of the lower longitudinal beam 2 of the rear cabin, and an insertion groove 201 is provided on the convex portion, and the front end of the connecting beam 6 is inserted into the insertion groove 201 and connected to the lower longitudinal beam 2 of the rear cabin.

[0067] As a preferred embodiment, Figure 7 and Figure 8 As shown in , the second mounting bracket 202 of this embodiment includes two mounting plates 2021 arranged at intervals along the front-rear direction of the vehicle, and a bottom plate 2022 provided between the bottoms of the two mounting plates 2021. In addition, to improve the mounting strength, a rib plate 2023 is provided between each side mounting plate 2021 and the rear compartment lower longitudinal beam 2. The power assembly can be connected to the two mounting plates 2021 by fasteners such as bolts.

[0068] In addition, if Figure 1 As shown in , as a further embodiment, the connecting beam 6 extends upward and backward and is connected to the middle of the rear shock tower 1. This design is conducive to the transmission of the rear impact force at the rear shock tower 1 in the direction pointing to the bottom of the cabin, which can reduce the intrusion of the rear cabin into the cabin and help improve the safety of rear impact. At this time, in order to further improve the overall strength and rigidity of the side structure of the vehicle rear cabin, as shown in Fig. 9 As shown in , the interior of the connecting beam 6 is divided into a plurality of cavities, each of which extends along its length direction, so that the connecting beam 6 has a better structural strength, thereby being able to improve the supporting effect between the rear shock tower 1 and the lower longitudinal beam 2 of the rear cabin.

[0069] Combination Figures 1 to 3As shown in , as a further embodiment, a second cross beam 4 is connected between the tops of the rear shock towers 1 on both sides, and a third cross beam 5 is connected between the bottoms of the rear shock towers 1 on both sides. Moreover, in the vertical direction of the whole vehicle, the first cross beam 3 is located between the second cross beam 4 and the third cross beam 5. In this embodiment, by providing the second cross beam 4 and the third cross beam 5, the lateral stiffness between the rear shock towers 1 on both sides can be increased, which helps to improve the stiffness at the first mounting bracket 7.

[0070] In addition, for the convenience of processing and manufacturing, the cross section of the second cross beam 4 of this embodiment is rectangular. Of course, the cross section of the second cross beam 4 can be circular or in other shapes in addition to being rectangular. Figure 3 and Fig.10 As shown in , the cross section of the third cross beam 5 of this embodiment is flat, and the cross section is roughly in the shape of a long strip extending along the front-rear direction of the vehicle. This design can not only increase the connection area between the third cross beam 5 and the rear shock tower 1, so as to better increase the overall rigidity of the rear part of the vehicle body. At the same time, it can also fully reduce the space occupied by the third cross beam 5 in the upper and lower directions of the vehicle, which is conducive to the installation of other components on the vehicle body.

[0071] In order to further enhance the lateral support function of the third cross beam 5, continue to refer to Fig.10 As shown in , a plurality of partition ribs are provided in the lower cross beam, and the partition ribs divide the interior of the third cross beam 5 into a plurality of sub-cavities arranged in sequence along the front-rear direction of the vehicle. Such a configuration not only makes the third cross beam 5 have a good structural strength, but also can further improve the overall rigidity of the rear part of the vehicle body.

[0072] Combination Figure 3 and Fig.10 As shown in , in this embodiment, as a further implementation, a first connecting plate 11 and a second connecting plate 12 are connected between the third cross beam 5 and each side rear shock tower 1. The first connecting plate 11 is arranged horizontally and connected between the third cross beam 5 and the bottom of the rear shock tower 1. Specifically, as Figure 3 and Fig.10 As shown in FIG. 1 , as a preferred embodiment, the first connecting plate 11 of this embodiment is triangular in shape, so as to utilize the high strength of the triangular structure to further increase its connection strengthening capability.

[0073] In addition, combined Figure 3 and Fig.10 As shown in , the second connecting plate 12 of this embodiment is arranged vertically and connected between the side of the third cross beam 5 and the inner side of the rear shock absorber tower 1, and the inner side of the rear shock absorber tower 1 is the side of the rear shock absorber tower 1 facing the inside of the vehicle in the left-right direction of the vehicle. Figure 4As shown in FIG. 1 , as a preferred embodiment, the second connecting plate 12 of this embodiment is triangular in shape, so as to utilize the high strength of the triangular structure to further increase its connection strengthening capability.

[0074] Here, it should be noted that the shapes of the first connecting plate 11 and the second connecting plate 12 are not limited to the triangle shown in the figure. In specific implementation, the first connecting plate 11 or the second connecting plate 12 can be set to a rectangular, circular or other shape according to design requirements. In addition, it should also be mentioned that in addition to designing the first connecting plate 11 and the second connecting plate 12 at the same time, only the first connecting plate 11 or the second connecting plate 12 can be set according to design requirements.

[0075] Still refer to Figures 1 to 3 As shown in , as a further embodiment, a fourth cross beam 8 is connected between the lower longitudinal beams 2 of the rear compartment on both sides, and the fourth cross beam 8 is arranged close to the second mounting bracket 202. In this embodiment, by arranging the fourth cross beam 8, the lateral rigidity between the lower longitudinal beams 2 of the rear compartment on both sides can be increased, which is conducive to improving the rigidity at the second mounting bracket 202. In particular, in order to facilitate processing and manufacturing, the cross section of the fourth cross beam 8 of this embodiment is rectangular. Of course, in addition to being rectangular, the cross section of the fourth cross beam 8 can also be circular or other shapes.

[0076] Continue to refer to Figures 1 to 3 In the embodiment, as a further implementation, reinforcing longitudinal beams 9 are respectively connected between the fourth cross beam 8 and the bottom of the rear shock towers 1 on both sides, and the front ends of the reinforcing longitudinal beams 9 on both sides are arranged close to the middle of the fourth cross beam 8 in the left-right direction. In this embodiment, by setting the reinforcing longitudinal beams 9, not only can the connection between the lower longitudinal beams 2 of the rear cabin on each side and the rear shock tower 1 be strengthened by the reinforcing longitudinal beams 9, thereby improving the overall rigidity of the lower part of the rear cabin, but also the force transmission channel can be increased when the vehicle collides, which helps to improve the collision force transmission effect. By setting the front ends of the reinforcing longitudinal beams 9 on both sides close to the middle of the second cross beam 4, the reinforcing longitudinal beams 9 on both sides can be arranged in an "eight" shape, which is conducive to improving the reinforcing effect of the reinforcing longitudinal beams 9.

[0077] In order to facilitate processing and manufacturing, the cross section of the reinforcing longitudinal beam 9 of this embodiment is rectangular. Of course, the cross section of the reinforcing longitudinal beam 9 can be set to a circular shape or other shapes in addition to a rectangular shape. In addition, as a further embodiment, Figure 1 and Figure 3 As shown in the figure, each reinforced longitudinal beam 9 of this embodiment is connected to the second cross beam 4 through a connecting bracket 10. This design can facilitate the connection between the reinforced longitudinal beam 9 and the second cross beam 4. As a preferred embodiment, in order to improve the connection firmness between the reinforced longitudinal beam 9 and the fourth cross beam 8, as shown in the figure, Fig.11 As shown in FIG. 1 , the structure of the connecting bracket 10 of this embodiment is as follows: Fig.11As shown in , a groove 1001 adapted to the front end of the reinforcing longitudinal beam 9 is formed at its rear end, and the front end is used to be connected to the second cross beam 4.

[0078] In addition, in order to improve the connection effect between the reinforcing longitudinal beam 9 and the fourth cross beam 8, as a further embodiment, the cross section of the connecting bracket 10 is gradually increased from the back to the front. In this way, the connection area between the connecting bracket 10 and the second cross beam 4 can be increased, and the two can be connected by welding. At the same time, the front end of the reinforcing longitudinal beam 9 is inserted into the groove 1001 and connected to the connecting bracket 10 by welding. In this embodiment, in order to further improve the connection strength, Fig.11 As shown in , a plurality of ribs are provided on the connecting bracket 10 to further improve the structural strength of the connecting bracket 10 , thereby improving the connection strength between the reinforcing longitudinal beam 9 and the fourth cross beam 8 .

[0079] The powertrain installation structure of this embodiment, by adopting the above structure, can not only realize the installation arrangement of the powertrain in the rear cabin of the vehicle, but also can utilize the high strength of the triangular structure to ensure the stability of the powertrain installation, which helps to improve the quality of the entire vehicle.

[0080] In addition, the present embodiment also relates to a vehicle, in which the above powertrain installation structure is provided.

[0081] Among them, as a preferred embodiment, combined with Figure 1 , Fig.12 and Fig.13 As shown in , the rear shock absorber towers 1 on both sides of this embodiment are integrally cast, and are annular, and are respectively provided with a through hole K for the transmission shaft to pass through, a shock absorber mounting portion, and a plurality of swing arm mounting portions on each rear shock absorber tower 1. In addition, the shock absorber mounting portion is located at the top of the rear shock absorber tower 1, and the plurality of swing arm mounting portions are arranged around the through hole K.

[0082] In this embodiment, the rear shock tower 1 is integrally cast, which can facilitate the preparation of the rear shock tower 1, reduce the preparation cost, and ensure the structural strength of the rear shock tower 1. By setting the rear shock tower 1 in a ring shape and arranging a shock absorber mounting portion and a swing arm mounting portion on the rear shock tower 1, not only can the structural strength of the rear shock tower 1 be increased by utilizing the high strength of the ring structure, but it can also facilitate the preparation of the rear shock tower 1 and reduce the preparation cost. At the same time, it can also facilitate the integrated design of the installation structure on the rear shock tower 1, which helps to reduce the difficulty of designing and preparing the installation structure, and can improve the comprehensive performance of the rear shock tower 1.

[0083] Specifically, combined with Fig.12 and Fig.13As shown in , the through hole K for the transmission shaft to pass through is roughly a long hole extending in the vertical direction of the vehicle. The rear shock tower 1 is arranged in the shape of the through hole K, and a protruding portion protruding upward is provided on the top of the rear shock tower 1, and the protruding portion is used to connect with the vehicle cabin. In addition, as shown in Figure 3 As shown in , the rear shock tower 1 is provided with a side plate arranged along its edge, so that the rear shock tower 1 has a good structural strength. In addition, the side plate extends to one side of the vehicle interior to improve the aesthetics of the rear shock tower 1 and also reduce the occupied space.

[0084] In addition, as a preferred embodiment, in this embodiment, in the left and right directions of the vehicle, Figure 1 and Figure 2 As shown in , the shock absorber mounting part and each swing arm mounting part are arranged on the side of the rear shock absorber tower 1 facing the outside of the vehicle, and a plurality of reinforcing ribs 105 are arranged on the side of the rear shock absorber tower 1 facing the inside of the vehicle. By arranging the reinforcing ribs 105 on the rear shock absorber tower 1, the structural strength of the rear shock absorber tower 1 can be increased, the reliability of the vehicle suspension installation in the vehicle body can be improved, and the overall rigidity of the vehicle body can also be improved. In addition, as a preferred embodiment, the reinforcing ribs 105 are connected to the above-mentioned side plates, and are multiple interlaced and connected, so as to better improve the structural strength of the rear shock absorber tower 1.

[0085] Specifically, combined with Figure 1 and Fig.12 As shown in , the swing arm mounting parts of this embodiment are five and are arranged at intervals along the circumference of the through hole K. It is understandable that, in specific implementation, the number of swing arm mounting parts can be adjusted accordingly according to design requirements. In addition, as a specific embodiment, the shock absorber mounting part of this embodiment includes a shock absorber mounting boss 1011 arranged on the rear shock absorber tower 1, and the shock absorber mounting boss 1011 is provided with a shock absorber mounting hole. The shock absorber mounting boss 1011 is arranged on the above-mentioned protruding part, and in order to improve the installation stability of the shock absorber, as shown in FIG. Figure 3 As shown in FIG. 1 , there are two shock absorber mounting bosses 1011 arranged opposite to each other.

[0086] In addition, as a further embodiment, Figure 1 and Fig.12 As shown in , the rear shock absorber tower 1 is provided with a shock absorber avoidance groove 101, and the shock absorber mounting boss 1011 is located in the shock absorber avoidance groove 101. The provision of the shock absorber avoidance groove 101 is not only conducive to the installation and arrangement of the shock absorber on the rear shock absorber tower 1, but also makes each shock absorber mounting boss 1011 located in the shock absorber avoidance groove 101, which also helps to reduce the protruding height of the shock absorber mounting boss 1011, reduce the overall volume of the rear shock absorber tower 1, and facilitate its arrangement in the vehicle.

[0087] In addition, as a further embodiment, in combination with Figure 1 and Fig.13 As shown in , the rear shock absorber tower 1 is provided with a reinforcing rib 1012 connected to the shock absorber mounting boss 1011, and the reinforcing rib 1012 is arranged along the height direction of the rear shock absorber tower 1. The reinforcing rib 1012 is arranged one-to-one with the shock absorber mounting boss 1011. In this embodiment, by providing the reinforcing rib 1012 connected to the shock absorber mounting boss 1011 and arranged along the height direction of the rear shock absorber tower 1, the stiffness of the shock absorber mounting point can be increased, and the reliability of the shock absorber installation can be improved. In order to further improve the installation reliability of the shock absorber, the reinforcing rib 1012 of this embodiment is triangular, so as to utilize the high strength of the triangular structure to further improve the reinforcement effect.

[0088] Continue to refer to Fig.12 As shown in , each swing arm mounting part of this embodiment includes a swing arm mounting boss 1021 disposed on the rear shock absorber tower 1, and a swing arm mounting hole is provided on the swing arm mounting boss 1021. The swing arm mounting part of this embodiment adopts a swing arm mounting boss 1021 with a swing arm mounting hole disposed on the rear shock absorber tower 1, which has a simple structure, is easy to form, and is also conducive to the installation operation of the swing arm. In addition, in order to improve the installation firmness of the swing arm, as shown in FIG. Figure 1 As shown in , as a preferred embodiment, each swing arm mounting portion includes two swing arm mounting bosses 1021 arranged opposite to each other.

[0089] In addition, in order to further improve the use effect of the shock tower structure, such as Fig.12 As shown in , as a further embodiment, a swing arm avoidance groove 102 is provided on the rear shock absorber tower 1, and a swing arm mounting boss 1021 is located in the swing arm avoidance groove 102. Such a design is not only conducive to the installation and arrangement of the swing arm on the rear shock absorber tower 1, but also helps to reduce the protruding height of the swing arm mounting boss 1021, which can reduce the overall volume of the rear shock absorber tower 1 and facilitate its arrangement in the vehicle.

[0090] Here, it should be noted that, in addition to setting the shock absorber avoidance groove 101 and the swing arm avoidance groove 102 at the same time as above, it is also possible to only set the shock absorber avoidance groove 101 according to design requirements, that is, in this case, the swing arm mounting boss 1021 protrudes toward the outside of the vehicle relative to the rear shock absorber tower 1. In addition, it is also possible to only set the swing arm avoidance groove 102 according to design requirements, that is, in this case, the shock absorber mounting boss 1011 protrudes toward the outside of the vehicle relative to the rear shock absorber tower 1. This setting will obviously increase the space occupied by the rear shock absorber tower 1 on the whole vehicle.

[0091] In addition, combined Figure 1 and Fig.12 As shown in FIG. 1 , the front end of the rear shock tower 1 is provided with a mounting groove 103 for connecting with the connecting beam 6, and as a preferred embodiment, the mounting groove 103 of this embodiment is roughly triangular. Fig.13As shown in FIG. 1 , a connecting groove 106 is provided on the inner side of the rear shock tower 1 , and the connecting groove 106 is provided for the end of the first cross beam 3 to be embedded, and can be specifically welded to the end of the first cross beam 3 . Fig.13 As shown in , in order to improve the connection strength between the rear shock tower 1 and the first cross beam 3, a plurality of interlaced ribs are provided in the connection groove 106 to improve the structural strength of this part, thereby improving the installation firmness of the first cross beam 3 and further improving the installation firmness of the powertrain.

[0092] It should be noted that, in addition to providing the mounting grooves 103 on both sides of the rear shock absorber towers 1 and embedding the ends of the connecting beams 6 into the mounting grooves 103, it is also feasible not to provide the mounting grooves 103 on the rear shock absorber towers 1 and directly connect the connecting beams to the sides of the rear shock absorber towers 1.

[0093] In addition, in order to facilitate the connection between the first connecting plate 11 and the rear shock tower 1, as shown in FIG. Fig.10 and Fig.11 As shown in , a downwardly extending mounting post 104 is provided at the bottom of the rear shock tower 1, and the first connecting plate 11 is connected between the mounting post 104 and the bottom of the third cross beam 5. Moreover, as a specific embodiment, a threaded hole is provided on the mounting post 104, one end of the first connecting plate 11 is welded to the bottom of the third cross beam 5, and the other end is screwed to the mounting post 104 by bolts.

[0094] The vehicle of this embodiment, by adopting the above structure, can ensure the stability of the power assembly installation, which helps to improve the quality of the entire vehicle.

[0095] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
