[0020] Secondly, by making the projection contour of the end portion of the second cross beam larger than the projection contour of the middle portion, the larger cross-sectional size of the end portion of the second cross beam can be utilized to increase the stability of the connection between it and the rear shock absorber tower. By providing a reinforced longitudinal beam, not only can the connection between the longitudinal beam and the first cross beam on each side of the rear cabin be utilized to enhance the overall rigidity of the upper portion of the rear cabin, but also a force transmission channel can be added between the vehicle cabin and the first cross beam and the rear shock absorber tower when the vehicle collides, which helps to improve the collision force transmission effect.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0052] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0053] In view of the existing rear-mounted vehicle models, especially high-performance vehicles with low streamlined bodies, the rear-mounted powertrain is generally installed on the vehicle body through the suspension mounting points located on the side thereof, which is easy to affect the installation arrangement of the powertrain due to the difficulty in setting the suspension mounting points, and is also not conducive to improving the installation stability of the powertrain. Therefore, this embodiment particularly relates to a new type of vehicle rear cabin upper structure, which includes a first crossbeam 2 and a second crossbeam 3 connected between the upper parts of the left and right rear shock towers 1, and a rear cabin upper longitudinal beam 5 connected between the rear shock towers 1 on each side and the vehicle cabin 9.

[0054] Furthermore, in the up-down direction of the vehicle, the second cross beam 3 is arranged lower than the first cross beam 2, and a powertrain suspension mounting bracket 7 is provided on the second cross beam 3, and the first cross beam 2, the second cross beam 3 and the rear shock towers 1 on both sides are connected to form an annular structure.

[0055] The upper structure of the vehicle rear compartment of this embodiment can install the powertrain from the top of the powertrain by setting the powertrain suspension installation point on the second crossbeam 3, which can facilitate the installation and layout of the powertrain. At the same time, the first crossbeam 2, the second crossbeam 3, and the rear shock towers 1 on both sides are connected to form an annular structure, which can increase the rigidity of the powertrain suspension installation point by taking advantage of the high strength of the annular structure, which helps to improve the stability of the powertrain arrangement in the vehicle and is conducive to improving the quality of the entire vehicle.

[0056] Based on the above overall introduction, an exemplary structure of the vehicle rear compartment upper structure of this embodiment is referred to as Figures 1 to 3 As shown in , in a preferred embodiment, the first cross beam 2 is connected to the top surface of the rear shock tower 1 on each side. Such a configuration is conducive to the arrangement of the first cross beam 2 and the connection between the first cross beam 2 and the rear shock tower 1, and is also conducive to avoiding surrounding parts and reducing the difficulty of arranging the vehicle parts. In addition, for the convenience of processing and manufacturing, the cross section of the first cross beam 2 of this embodiment is rectangular. Of course, in addition to being rectangular, it is also feasible to set the cross section of the first cross beam 2 to be circular or other shapes.

[0057] In addition, as a preferred embodiment, connecting grooves 106 are provided on the rear shock towers 1 on both sides, and the ends of the second cross beam 3 are embedded in the connecting grooves 106. Such an arrangement can increase the reliability of the connection between the second cross beam 3 and the rear shock towers 1 on both sides. It should be noted here that, in addition to connecting the first cross beam 2 to the top surface of the rear shock towers 1 on each side, it is also feasible to connect it to the side surfaces of the rear shock towers 1 on both sides. In addition, in addition to providing the connecting grooves 106 on the rear shock towers 1 on both sides and embedding the ends of the second cross beam 3 into the connecting grooves 106, it is also feasible not to provide the connecting grooves 106 on the rear shock towers 1, and directly connect the second cross beam 3 to the side surfaces of the rear shock towers 1.

[0058] Combination Figures 1 to 4 As shown in , as a preferred embodiment, the second 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. Among them, the powertrain suspension mounting bracket 7 is arranged on the middle portion 301, and the outline of each end portion 302 projected in the left and right direction of the whole vehicle is larger than the outline of the middle portion 301 projected in the left and right direction of the whole vehicle. In this embodiment, by making the projection outline of the end portion 302 of the second cross beam 3 larger than the projection outline of the middle portion 301, the larger cross-sectional size of the end of the second cross beam 3 can be used to increase the stability of the connection between it and the rear shock tower 1.

[0059] like Figure 4 As shown in , in order to further improve the lateral support effect of the second 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 second cross beam 3 have a higher structural strength and better connection reliability with the rear shock tower 1.

[0060] As a specific implementation, the structure of the powertrain suspension mounting bracket 7 of this embodiment is as follows: Figure 5 and Figure 6 As shown in FIG. , the front end has a groove adapted to the second cross beam 3, and the rear end has two connecting ears arranged opposite to each other, and each connecting ear is provided with a connecting hole. The rear end of the second cross beam 3 is embedded in the groove and welded to the powertrain suspension mounting bracket 7, and the powertrain suspension can be connected to the two connecting ears by bolts. Of course, the structure of the powertrain suspension mounting bracket 7 is not limited to Figure 5 The structure shown in can be adjusted accordingly according to design requirements.

[0061] Combination Figures 1 to 3As shown in , as a further implementation, a reinforcing longitudinal beam 4 is connected between the upper longitudinal beam 5 of the rear cabin on each side and the first cross beam 2. Moreover, from the vertical direction of the whole vehicle, the reinforcing longitudinal beams 4 on each side are cross-arranged between the upper longitudinal beams 5 of the rear cabin on the same side, and the front end of the reinforcing longitudinal beams 4 on each side is connected to the front end of the upper longitudinal beam 5 of the rear cabin on the same side, and the rear end of the reinforcing longitudinal beams 4 on each side is connected to the first cross beam 2. In this embodiment, by providing the reinforcing longitudinal beams 4, not only can the connection between the upper longitudinal beams 5 of the rear cabin on each side and the first cross beam 2 of the reinforcing longitudinal beams 4 be utilized to improve the overall rigidity of the upper part of the rear cabin, but also, when the vehicle collides, a force transmission channel can be added between the vehicle cabin 9 and the first cross beam 2 and the rear shock tower 1, which helps to improve the collision force transmission effect.

[0062] As a preferred embodiment, Figure 1 and Figure 3 As shown in , the rear ends of the two side reinforcing longitudinal beams 4 are arranged close to the middle of the first cross beam 2 in the left-right direction, and each reinforcing longitudinal beam 4 is connected to the first cross beam 2 through a connecting bracket 8. In this embodiment, the rear ends of the two side reinforcing longitudinal beams 4 are arranged close to the middle of the first cross beam 2, so that the two side reinforcing longitudinal beams 4 are arranged in an "eight" shape, which is conducive to improving the reinforcing effect of the reinforcing longitudinal beams 4. The reinforcing longitudinal beams 4 are connected to the first cross beam 2 through the connecting bracket 8, which can facilitate the connection between the reinforcing longitudinal beams 4 and the first cross beam 2.

[0063] Among them, as a preferred embodiment, in order to facilitate processing and manufacturing, the cross-section of the reinforcing longitudinal beam 4 of this embodiment is rectangular. Of course, in addition to setting the cross-section of the reinforcing longitudinal beam 4 to a rectangular shape, it is also feasible to set it to a circular shape or other shapes.

[0064] In addition, as a preferred embodiment, the structure of the connecting bracket 8 of this embodiment is as follows: Figure 7 As shown in , a slot adapted to the rear end of the reinforcing longitudinal beam 4 is formed at its front end, and the rear end is used to connect with the first cross beam 2. In addition, in order to improve the connection effect between the reinforcing longitudinal beam 4 and the first cross beam 2, as a further embodiment, the cross section of the connecting bracket 8 is gradually increased from the front to the rear. Thereby, the connection area between the connecting bracket 8 and the first cross beam 2 can be increased, and the two can be connected by welding. At the same time, the rear end of the reinforcing longitudinal beam 4 is inserted into the slot and connected to the connecting bracket 8 by welding.

[0065] In this embodiment, in order to further improve the connection strength, Figure 7 As shown in , a plurality of ribs are provided on the connecting bracket 8 to further improve the structural strength of the connecting bracket 8 , thereby improving the connection strength between the reinforcing longitudinal beam 4 and the first cross beam 2 .

[0066] As a further embodiment, Figures 1 to 3As shown in , the front end of each side rear cabin upper longitudinal beam 5 is provided with a connecting seat 6, and each side rear cabin upper longitudinal beam 5 is connected to the vehicle cabin 9 through the connecting seat 6, and the front end of each side reinforcing longitudinal beam 4 is connected to the same side connecting seat 6. In this embodiment, by providing the connecting seat 6, it is not only convenient to connect the rear cabin upper longitudinal beam 5 and the vehicle cabin 9, but also helpful to connect the rear cabin upper longitudinal beam 5 and the reinforcing longitudinal beam 4.

[0067] Furthermore, as a preferred embodiment, the structure of the connecting seat 6 of this embodiment refers to Figure 8 and Fig. 9 As shown in the figure, it includes a front plate 601 connected to the vehicle cabin 9, a bottom plate 602 arranged at the bottom of the front plate 601, a side plate 604 arranged below the bottom plate 602, and a folding plate 603 arranged between the front plate 601 and the bottom plate 602. In addition, a first slot body 605 and a second slot body 606 are formed between the folding plate 603 and the front plate 601 and the bottom plate 602, and the first slot body 605 and the second slot body 606 are respectively arranged on two opposite sides of the folding plate 603.

[0068] In addition, the top of the front plate 601 has a flange bent backwards, which can not only improve its structural strength, but also facilitate connection with other components. The connecting seat 6 of this embodiment is specifically riveted to the vehicle cabin 9 through rivets in the first slot 605, and the front end of the rear cabin upper longitudinal beam 5 is inserted into the second slot 606 and welded to the connecting seat 6. The connection by welding can better improve the overall rigidity of the rear of the vehicle. In addition, the front end of the reinforcing longitudinal beam 4 is inserted between the front plate 601 and the flange, and is welded to the front plate 601 and the flange.

[0069] It should be noted that the connection between the reinforcing longitudinal beam 4 and the first cross beam 2 and the connecting seat 6 may be connected by other means such as screw connection in addition to welding. In addition, in addition to connecting the reinforcing longitudinal beam 4 and the first cross beam 2 through the connecting bracket 8, the connecting bracket 8 may not be provided, and the reinforcing longitudinal beam 4 and the first cross beam 2 may be directly connected. Similarly, the connecting seat 6 may not be provided, and the rear cabin upper longitudinal beam 5 may be connected to the vehicle cabin 9.

[0070] In addition, as a further embodiment, the first cross beam 2, the second cross beam 3, and at least one of the rear cabin upper longitudinal beam 5 and the reinforcing longitudinal beam 4 in this embodiment adopts an extruded profile. As a preferred embodiment, the rear cabin upper longitudinal beam 5, the first cross beam 2, the second cross beam 3 and the reinforcing longitudinal beam 4 in this embodiment all adopt an extruded profile, which is conducive to the preparation of each component, and also helps to ensure their structural strength, and is conducive to improving the overall rigidity of the rear cabin side.

[0071] It should be noted that, in addition to using extruded profiles for the upper longitudinal beam 5, the first cross beam 2, the second cross beam 3 and the reinforcing longitudinal beam 4, only some of the components may be made of extruded profiles, and generally may be made of extruded aluminum profiles. Alternatively, the upper longitudinal beam 5, the first cross beam 2, the second cross beam 3 and the reinforcing longitudinal beam 4 of the rear cabin are made by machining.

[0072] In addition, at least one of the connection seat 6 and the connection bracket 8 is cast. As a preferred embodiment, the connection seat 6 and the connection bracket 8 of this embodiment are both cast, so as to facilitate the preparation of the connection seat 6 and the connection bracket 8, and also ensure their structural strength. It should be noted that in addition to casting the connection seat 6 and the connection bracket 8, the connection seat 6 and the connection bracket 8 can also be made by machining.

[0073] The upper structure of the rear compartment of the vehicle of this embodiment, by adopting the above structure, is convenient for the installation and arrangement of the powertrain. At the same time, it can also increase the rigidity of the powertrain suspension installation point, help improve the stability of the powertrain arrangement in the vehicle, and help improve the quality of the entire vehicle.

[0074] In addition, the present embodiment also relates to a vehicle, in which the vehicle rear cabin upper structure as described above is provided.

[0075] Still refer to Figures 1 to 3 , and combined with Fig.10 and Fig.11 As shown in , as a preferred embodiment, the rear shock absorber towers 1 on both sides of this embodiment are integrally cast, and the rear shock absorber towers 1 on both sides are annular, and each rear shock absorber tower 1 is 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. 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.

[0076] 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.

[0077] Specifically, combined with Figure 3 and Figure 4As 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 9. 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 door to improve the aesthetics of the rear shock tower 1 and also reduce the occupied space.

[0078] 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.

[0079] Specifically, combined with Figure 3 and Figure 4 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.

[0080] In addition, as a further embodiment, Figure 3 and Figure 4 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 mounting boss located in the avoidance groove, which also helps to reduce the protruding height of the mounting boss, reduce the overall volume of the rear shock absorber tower 1, and facilitate its arrangement in the vehicle.

[0081] In addition, as a further embodiment, in combination with Figure 3As 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.

[0082] Continue to refer to Figure 3 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.

[0083] In addition, in order to further improve the use effect of the rear shock tower 1, as Figure 1 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 mounting boss, which can reduce the overall volume of the rear shock absorber tower 1 and facilitate its arrangement in the vehicle.

[0084] 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.

[0085] Combination Fig.10 and Fig.11As shown in FIG, in addition to the above-mentioned connection groove 106 provided on the inner side of the rear shock absorber tower 1, in this embodiment, in order to facilitate the connection between the rear shock absorber tower 1 and the vehicle cabin 9 in front of it, two front mounting grooves 103 arranged in an upper and lower interval are provided at the front end of the rear shock absorber tower 1. Correspondingly, a rear mounting groove 104 is provided at the rear end of the rear shock absorber tower 1 to facilitate the connection between the rear shock absorber tower 1 and the longitudinal beam behind it. In addition, still referring to FIG. Fig.11 As shown in , in order to improve the connection strength between the rear shock tower 1 and the second 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 second cross beam 3 and further improving the installation firmness of the powertrain.

[0086] The vehicle of this embodiment, by adopting the above structure, is convenient for the installation and arrangement of the powertrain, and can increase the rigidity of the powertrain suspension installation point, which helps to improve the stability of the powertrain arrangement in the vehicle and is beneficial to improving the quality of the entire vehicle.

[0087] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
