[0046] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0047] In view of the existing rear cabin side structure of vehicles, the structural strength still needs to be strengthened, and when the vehicle collides, the collision force transmission channel is single, which is not conducive to improving the collision safety of the whole vehicle. Therefore, this embodiment proposes a new vehicle rear cabin side structure, which includes a rear cabin upper longitudinal beam 2, a rear cabin lower longitudinal beam 4, a rear shock tower 1, and a first connecting beam 5 and a second connecting beam 6.

[0048] Among them, the front ends of the rear cabin upper longitudinal beam 2 and the rear cabin lower longitudinal beam 4 are both connected to the vehicle cabin 7, the rear end of the rear cabin upper longitudinal beam 2 is connected to the top of the rear shock tower 1, and the rear end of the rear cabin lower longitudinal beam 4 is connected to the front end of the first connecting beam 5. The rear end of the first connecting beam 5 extends upward and backward and is connected to the middle of the rear shock tower 1, and the second connecting beam 6 is connected between the rear cabin upper longitudinal beam 2 and the rear cabin lower longitudinal beam 4. In addition, from the left and right direction of the whole vehicle, the rear cabin upper longitudinal beam 2, the first connecting beam 5 and the second connecting beam 6 form a triangular frame structure under the connection of the rear cabin lower longitudinal beam 4 and the rear shock tower 1.

[0049] The vehicle rear compartment side structure of the present embodiment forms a triangular frame structure by connecting the rear compartment upper longitudinal beam 2, the first connecting beam 5 and the second connecting beam 6 under the connection of the rear compartment lower longitudinal beam 4 and the rear shock tower 1. The high strength of the triangular structure can be used to increase the structural strength of the rear compartment side and the ability to transmit collision force, thereby helping to improve the safety of the entire vehicle.

[0050] Based on the above overall introduction, an exemplary structure of the vehicle rear compartment side structure of this embodiment is referred to as Figure 1 and Figure 2 As shown in , and based on the fact that a vehicle is generally a left-right symmetrical structure, in order to clearly illustrate the inventive point of this embodiment, Figure 1 and Figure 2 Only the rear cabin side structure on the left side of the vehicle is illustrated, and the rear cabin side structure on the right side of the vehicle can be set as described below, which will not be repeated here. In this embodiment, as a preferred implementation, the rear shock tower 1 is integrally cast, and the rear shock tower 1 and the upper longitudinal beam 2 of the rear cabin, as well as the rear shock tower 1 and the first connecting beam 5 are connected by welding and riveting.

[0051] By integrally casting the rear shock tower 1, the preparation of the rear shock tower 1 can be facilitated, the preparation cost can be reduced, and the structural strength of the rear shock tower 1 can be ensured. At the same time, the upper longitudinal beam 2 of the rear cabin and the first connecting beam 5 are connected to the rear shock tower 1 by welding and riveting, which can improve the connection strength and ensure the reliability of the connection. It should be noted that in addition to connecting the rear shock tower 1 and the upper longitudinal beam 2 of the rear cabin by welding and riveting, and connecting the rear shock tower 1 and the first connecting beam 5 by welding and riveting. The rear shock tower 1 and the upper longitudinal beam 2 of the rear cabin can also be connected only by welding or riveting, or the rear shock tower 1 and the first connecting beam 5 can be connected only by welding or riveting.

[0052] Combination Figure 3 and Figure 4 As shown in , as a preferred embodiment, the rear shock absorber tower 1 is annular, and a through hole K for the transmission shaft to pass through is provided on the rear shock absorber tower 1, and a shock absorber mounting portion and a plurality of swing arm mounting portions are provided on the rear shock absorber tower 1. Moreover, 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.

[0053] In this embodiment, by forming the rear shock tower 1 in an integral shape and in a ring shape, and arranging the shock absorber mounting portion and the swing arm mounting portion on the rear shock tower 1, not only can the strength of the shock tower structure 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.

[0054] Specifically, combined with Figure 3 and Figure 4 As 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 to the upper longitudinal beam 2 of the rear cabin. In addition, as shown in Figure 3As 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.

[0055] 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.

[0056] 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.

[0057] 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 shock absorber tower, but also allows each mounting boss to be 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.

[0058] 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.

[0059] 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.

[0060] 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 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.

[0061] 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.

[0062] In addition, in order to facilitate the connection between the rear shock tower 1 and the upper longitudinal beam 2 of the rear cabin, as a further implementation method, Figure 1 and 3 As shown in FIG. 1 , a first connecting groove 103 is provided on the top of the rear shock tower 1, and the rear end of the rear cabin upper longitudinal beam 2 is embedded in the first connecting groove 103. Figure 3As shown in , as a preferred embodiment, the first connection groove 103 is triangular in shape, so that the rear cabin upper longitudinal beam 2 can be inserted into the first connection groove 103. At the same time, the edge of the notch of the first connection groove 103 is welded to the rear cabin upper longitudinal beam 2, and the portion of the rear cabin upper longitudinal beam 2 inserted into the first connection groove 103 is riveted to the rear shock tower 1 by rivets. Moreover, further, the portion of the rear cabin upper longitudinal beam 2 inserted into the first connection groove 103 is riveted to the rear shock tower 1 by rivets in the vertical and horizontal directions of the whole vehicle, so as to fully improve the connection reliability between the two, which is conducive to ensuring the overall rigidity of the rear cabin side structure.

[0063] Similarly, in order to facilitate the connection between the rear shock tower 1 and the first connecting beam 5, still refer to Figure 1 and Figure 3 As shown in , the middle of the rear shock tower 1 is provided with a second connection groove 104, and the rear end of the first connection beam 5 is embedded in the second connection groove 104. The second connection groove 104 is also roughly triangular, so that the first connection beam 5 can be inserted into the second connection groove 104, and the edge of the notch of the second connection groove 104 is welded and connected to the first connection beam 5. At the same time, the two are riveted together in the vertical and left-right directions of the vehicle by rivets to fully improve the connection reliability between the two, which is conducive to ensuring the overall rigidity of the rear cabin side structure.

[0064] It should be noted that, in addition to setting both the first connecting groove 103 and the second connecting groove 104 on the rear shock absorber tower 1, only the first connecting groove 103 or the second connecting groove 104 can be set according to design requirements, as long as the connection between the rear shock absorber tower 1 and the upper longitudinal beam 2 of the rear cabin and the first connecting beam 5 can be achieved.

[0065] In this embodiment, combined with Figure 1 and Figure 2 As shown in the figure, as a preferred embodiment, a connecting seat 3 is provided at the front end of the upper longitudinal beam 2 of the rear cabin, the connecting seat 3 is connected to the vehicle cabin 7, and the upper end of the second connecting beam 6 is connected to the connecting seat 3. By providing the connecting seat 3, it is not only convenient to connect the upper longitudinal beam 2 of the rear cabin with the vehicle cabin 7, but also helpful to connect the upper longitudinal beam 2 of the rear cabin with other surrounding components.

[0066] Among them, as a preferred embodiment, the structure of the connecting seat 3 of this embodiment is combined with Figure 5 and Figure 6 As shown in the figure, it includes a front plate 301 connected to the vehicle cabin 7, a bottom plate 302 arranged at the bottom of the front plate 301, a side plate 304 arranged below the bottom plate 302, and a folding plate 303 arranged between the front plate 301 and the bottom plate 302. In addition, a first slot body 305 and a second slot body 306 are formed between the folding plate 303 and the front plate 301 and the bottom plate 302, and the first slot body 305 and the second slot body 306 are respectively arranged on two opposite sides of the folding plate 303.

[0067] In addition, the top of the front plate 301 has a flange bent backwards, which can not only improve its structural strength, but also facilitate connection with other components. The connecting seat 3 of this embodiment is riveted to the vehicle cabin 7 through rivets in the first slot 305, and the front end of the rear cabin upper longitudinal beam 2 is inserted into the second slot 306 and welded to the connecting seat 3.

[0068] like Figure 2 As shown in , the second connecting beam 6 of this embodiment is arranged vertically in the up-down direction of the whole vehicle, and the lower end of the second connecting beam 6 is arranged close to the rear end of the lower longitudinal beam 4 of the rear cabin. By arranging the second connecting beam 6 vertically, it can have a better vertical supporting capacity, can provide a better supporting effect between the upper longitudinal beam 2 of the rear cabin and the lower longitudinal beam 4 of the rear cabin, and ensure the stability of the upper and lower longitudinal beams of the rear cabin. At the same time, the lower end of the second connecting beam 6 is arranged close to the rear end of the lower longitudinal beam 4 of the rear cabin, which can also make the formed triangular frame structure have a better structural reinforcement effect. It should be noted that in addition to arranging the second connecting beam 6 vertically in the up-down direction of the whole vehicle, the second connecting beam 6 can also be arranged in a direction having a certain angle with the up-down direction of the whole vehicle.

[0069] In order to obtain a better use effect, as a preferred embodiment, the upper longitudinal beam 2, the first connecting beam 5 and the second connecting beam 6 of the rear cabin in this embodiment are made of extruded profiles, and the lower longitudinal beam 4 and the connecting seat 3 of the rear cabin are integrally cast. In addition, the upper longitudinal beam 2 and the connecting seat 3 of the rear cabin, the second connecting beam 6 and the connecting seat 3, the lower longitudinal beam 4 of the rear cabin, and the first connecting beam 5 and the lower longitudinal beam 4 of the rear cabin are all welded and connected. Among them, the upper longitudinal beam 2, the first connecting beam 5 and the second connecting beam 6 of the rear cabin can be made of extruded aluminum profiles.

[0070] In this embodiment, by using extruded profiles for the upper longitudinal beam 2, the first connecting beam 5, and the second connecting beam 6 of the rear cabin, and integrally casting the lower longitudinal beam 4 and the connecting seat 3, it is convenient to prepare the components and also helps to ensure their structural strength, so that the above components are welded and connected, which can ensure the connection strength between them and improve the overall rigidity of the side of the rear cabin. It should be noted that the upper longitudinal beam 2, the first connecting beam 5, and the second connecting beam 6 of the rear cabin, as well as the lower longitudinal beam 4 and the connecting seat 3 of the rear cabin can be made by other conventional methods in addition to the above process.

[0071] Specifically, combined with Figure 1 and Figure 6As shown in , the top of the second connecting beam 6 is welded to the bottom plate 302 of the connecting seat 3, and the side is welded to the side plate 304 of the connecting seat 3. Such an arrangement can further improve the firmness of the second connecting beam 6, thereby facilitating the stability of the upper and lower longitudinal beams of the rear cabin. It is understandable that in addition to welding the upper longitudinal beam 2 of the rear cabin and the connecting seat 3, the second connecting beam 6 and the connecting seat 3 and the lower longitudinal beam 4 of the rear cabin, and the first connecting beam 5 and the lower longitudinal beam 4 of the rear cabin, it is also feasible to connect them by screwing or riveting.

[0072] As a preferred embodiment, the structure of the rear compartment lower longitudinal beam 4 of this embodiment is as follows: Figure 7 As shown in , a groove is formed thereon with the notch facing the outside of the vehicle, and the groove extends along the length direction of the rear compartment lower longitudinal beam 4. In addition, in order to improve the structural strength of the rear compartment lower longitudinal beam 4, a plurality of staggered ribs are provided in the groove, and each rib is supported between the upper and lower side walls of the groove, thereby improving the strength of the rear compartment lower longitudinal beam 4 in the vertical direction of the whole vehicle.

[0073] In addition, in order to facilitate connection with the first connecting beam 5, as Figure 7 As shown in FIG. 4 , a rearwardly protruding convex portion is provided at the rear end of the lower longitudinal beam 4 of the rear compartment, and a mounting groove 401 is provided on the convex portion. Figure 1 and Figure 2 As shown in the figure, the front end of the first connecting beam 5 is inserted into the installation groove 401 and is welded to the edge of the installation groove 401. The rear cabin lower longitudinal beam 4 of this embodiment adopts the above structure, which is not only conducive to lightweight design, but also has good structural strength, which is conducive to improving the overall strength and rigidity of the vehicle rear cabin side structure. At this time, in order to further improve the overall strength and rigidity of the vehicle rear cabin side structure, as shown in the figure, Figure 8 As shown in , the interior of the first connecting beam 5 is divided into a plurality of cavities, each of which extends along its length direction, so that the first connecting beam 5 has a better structural strength, thereby being able to improve the supporting effect between the rear shock tower 1 and the lower longitudinal beam 4 of the rear cabin.

[0074] The vehicle rear compartment side structure of this embodiment can increase the structural strength of the rear compartment side by adopting the above structure, increase the ability to transmit collision force, and help improve the safety of the entire vehicle.

[0075] In addition, the present embodiment also relates to a vehicle, in which the vehicle rear compartment side structure as described above is provided.
