[0039] The rear floor longitudinal beam 1 is the main supporting structure of the vehicle chassis structure, and is used to enhance the torsional rigidity and impact resistance of the vehicle. When the vehicle collides, the rear floor longitudinal beam 1 can effectively absorb and disperse the impact energy to protect the safety of the vehicle occupants. The front section 2 of the rear floor longitudinal beam is used to connect other components, and is connected to the front end of the rear floor longitudinal beam 1, that is, the front section 2 of the rear floor longitudinal beam extends along the length direction and is connected to the front end of the rear floor longitudinal beam 1, forming an integral structure with the rear floor longitudinal beam 1, thereby enhancing the integrity and stability of the rear chassis structure of the vehicle.

[0040] The wheel arch upper side beam 3 is located above the rear floor longitudinal beam 1, the front end of the wheel arch upper side beam 3 is connected to the front section 2 of the rear floor longitudinal beam through the wheel arch front support beam 4, and the rear end of the wheel arch upper side beam 3 is connected to the rear floor longitudinal beam 1 through the wheel arch rear support beam 5 to jointly construct an upper ring structure.

[0041] Specifically, the wheel arch upper side beam 3 extends in the length direction and is located above the rear floor longitudinal beam 1, the upper end of the wheel arch front support beam 4 is connected to the front end of the wheel arch upper side beam 3, the lower end of the wheel arch front support beam 4 is connected to the front section 2 of the rear floor longitudinal beam, the upper end of the wheel arch rear support beam 5 is connected to the rear end of the wheel arch upper side beam 3, and the lower end of the wheel arch rear support beam 5 is connected to the rear end surface of the rear floor longitudinal beam 1, so that the wheel arch upper side beam 3, the rear floor longitudinal beam 1 and the front section 2 of the rear floor longitudinal beam are connected by the wheel arch front support beam 4 and the wheel arch rear support beam 5 to form a stable lower annular structure, thereby improving the rigidity, strength and torsional rigidity of the rear part of the vehicle.

[0042] The side edge beam 6 is located above the wheel arch upper edge beam 3, the front end of the wheel arch upper edge beam 3 is connected to the side edge beam 6 through the C-pillar reinforcement beam 7, and the rear end of the wheel arch upper edge beam 3 is connected to the rear end of the side edge beam 6 to jointly construct a lower annular structure, and the lower annular structure is located below the upper annular structure.

[0043] Specifically, the rear end of the side edge beam 6 is connected to the rear end of the wheel arch upper edge beam 3 and bends upward and extends forward. The C-pillar reinforcement beam 7 is located above the wheel arch front support beam 4, and its upper end is connected to the side edge beam 6, and the lower end is connected to the front end of the wheel arch upper edge beam 3. Therefore, the side edge beam 6 and the wheel arch upper edge beam 3 are connected by the C-pillar reinforcement beam 7, and the three together form a stable upper annular structure located above the side edge beam 6, which can further improve the stiffness, strength and torsional stiffness of the rear of the vehicle.

[0044] The upper annular structure and the lower annular structure respectively located above and below the upper side beam 3 of the wheel arch can reinforce each other to form a larger closed double annular structure, which greatly improves the stability, strength and rigidity of the structure near the side window and improves the torsional performance of the rear of the vehicle, thereby providing better protection and support for the occupants.

[0045] In actual design, the vehicle rear structure 100 may be composed of a die-cast structure and an extruded aluminum structure, and the rear floor longitudinal beam 1 may adopt an extruded aluminum profile structure, thereby ensuring the strength and stability of the vehicle rear structure 100 .

[0046] According to the vehicle rear structure 100 of the embodiment of the utility model, the lower annular structure formed by the wheel house upper side beam 3, the wheel house front support beam 4, the wheel house rear support beam 5, the front section of the rear floor longitudinal beam 2 and the rear floor longitudinal beam 1, and the upper annular structure formed by the side edge beam 6, the C-pillar reinforcement beam 7 and the wheel house upper side beam 3 can improve the rigidity, strength and torsional rigidity of the rear of the vehicle, so that the vehicle can effectively resist the impact and vibration from the road surface and reduce the deformation and damage of the vehicle body.

[0048] That is to say, the two sets of rear floor longitudinal beams 1, the front section of the rear floor longitudinal beam 2, the wheel house upper side beam 3, the side edge beam 6 and the C-pillar reinforcement beam 7 are respectively located on the left and right sides of the vehicle. In this way, the bottom and side structures of the rear of the vehicle are doubly reinforced, thereby increasing the overall rigidity of the vehicle. When the vehicle is hit while driving, the two sets of structures on the left and right sides can effectively resist the impact, improve the stability of the vehicle, reduce the deformation of the vehicle, further improve the torsional rigidity, and maintain the balance and stability of the vehicle to prevent one side from being subjected to excessive force.

[0049] A side window support beam 8 is connected between the wheel arch upper side beam 3 and the side surround side beam 6 of each group. The side window support beam 8 divides the upper ring structure into two sub-ring structures, and a shelf front cross beam 9 is connected between the two groups of side window support beams 8.

[0050] Specifically, Figure 1 and Figure 2 As shown, a side window support beam 8 is also provided at the middle position of the wheel arch upper side beam 3 to be connected with the side enclosure side beam 6. The side window support beam 8 is provided to support and connect between the wheel arch upper side beam 3 and the side enclosure side beam 6, so as to provide stable support for the vehicle side windows and ensure the firmness and stability of the side windows. At the same time, the side window support beam 8 divides the upper annular structure into two adjacent sub-annular structures. The two sub-annular structures can reinforce each other to further improve the strength and rigidity of the upper annular structure, thereby improving the local rigidity of the vehicle rear structure 100. A shelf front cross beam 9 is also connected between the middle positions of the two groups of side window support beams 8. The shelf front cross beam 9 is connected between the two groups of side window support beams 8, so that the shelf front cross beam 9 can be more firmly connected to the vehicle, thereby ensuring the stability and reliability of placing items on the shelf.

[0051] In some embodiments, a first wheel arch support beam 10 is provided between the front cross beam 9 of the shelf and the rear floor longitudinal beam 1 , and the first wheel arch support beam 10 is connected to the wheel arch upper side beam 3 at the bottom of the side window support beam 8 .

[0052] Specifically, the first wheel housing support beam 10 is used to enhance the installation strength and rigidity of the front cross beam 9 of the shelf. Fig. 9 and Fig.10 As shown, the first wheel arch support beam 10 extends vertically, with its upper end connected to the lower side of the front cross beam 9 of the shelf board, and the lower end connected to the upper side of the rear floor longitudinal beam 1, so that the first wheel arch support beam 10 is connected between the front cross beam 9 of the shelf board and the rear floor longitudinal beam 1, supports the front cross beam 9 of the shelf board, and enhances the stability of the front cross beam 9 of the shelf board, wherein the outer side of the first wheel arch support beam 10 is also connected to a wheel arch support cross beam 22, the wheel arch support cross beam 22 is connected between the first wheel arch support beam 10 and the wheel arch upper side beam 3 and is located at the bottom of the side window support beam 8, thereby enhancing the installation strength and stability of the wheel arch upper side beam 3, forming a multi-annular support reinforcement structure, thereby enhancing the strength and stability of the upper annular structure and the lower annular structure, and further improving the torsional rigidity of the vehicle.

[0053] In some embodiments, the vehicle rear structure 100 also includes a second wheel arch support beam 11, which is located on the rear side of the first wheel arch support beam 10, the upper end of the second wheel arch support beam 11 is connected to the upper end of the first wheel arch support beam 10, and the lower end of the second wheel arch support beam 11 is spaced apart from the first wheel arch support beam 10 and connected to the rear floor longitudinal beam 1.

[0054] Specifically, the second wheel housing support beam 11 is used to enhance the installation strength and rigidity of the front cross beam 9 of the shelf. Fig. 9 and Fig.10As shown, the second wheel house support beam 11 extends vertically, and its upper end is connected to the lower side of the front cross beam 9 of the shelf board, and the lower end is connected to the upper side of the rear floor longitudinal beam 1, so that the first wheel house support beam 10 is connected between the front cross beam 9 of the shelf board and the rear floor longitudinal beam 1, supporting the front cross beam 9 of the shelf board and enhancing the stability of the front cross beam 9 of the shelf board, wherein the front side of the second wheel house support beam 11 is connected to the rear side of the first wheel house support beam 10, and the second wheel house support beam 11 is extended obliquely so that the upper end of the second wheel house support beam 11 is connected to the upper end of the first wheel house support beam 10, so that the upper ends of the two overlap and are connected to the front cross beam 9 of the shelf board. The lower ends of the two are connected to the upper end of the rear floor longitudinal beam 1 at a certain distance, so that the first wheel house support beam 10, the second wheel house support beam 11 and the rear floor longitudinal beam 1 can be connected to form a triangular reinforcement structure. The triangular reinforcement structure has stronger stability, strength and rigidity, which can further enhance the stability, strength and rigidity of the rear structure 100 of the vehicle, thereby significantly improving the rigidity and stability of the bottom structure of the vehicle body, enhancing the torsional rigidity of the rear structure 100 of the vehicle, effectively resisting the impact and vibration from the road surface, and preventing the front cross beam 9 of the shelf board and other components from shaking and deformation, thereby reducing the deformation and damage of the vehicle body.

[0055] As well as Fig.10 As shown, a vertically extending wheel house support reinforcement beam is also provided between the first wheel house support beam 10 and the second wheel house support beam 11 to strengthen the strength and rigidity of the first wheel house support beam 10 and the second wheel house support beam 11, wherein the inclined extension direction of the second wheel house support beam 11 is the force transmission direction from the sub-frame mounting point to the rear shelf front cross beam 9, that is, the inclined setting of the second wheel house support beam 11 is conducive to the transmission of the force on the rear floor longitudinal beam 1 upward along the second wheel house support beam 11 to form a force transmission channel.

[0056] Therefore, if Fig.11 As shown, multiple force transmission channels can be formed at the rear part of the vehicle side enclosure, wherein the first transmission channel is: the force of the rear floor longitudinal beam 1 is transmitted to the front section 2 of the rear floor longitudinal beam, the second transmission channel is: the force of the rear floor longitudinal beam 1 is transmitted to the second wheel arch support beam 11, the third transmission channel is: the force of the rear floor longitudinal beam 1 is transmitted to the wheel arch rear support beam 5, and then transmitted from the wheel arch rear support beam 5 to the wheel arch upper side beam 3, the third transmission channel is: the force of the rear floor longitudinal beam 1 is transmitted to the wheel arch rear support beam 5, and then transmitted from the wheel arch rear support beam 5 to the side enclosure side beam 6. Multiple force transmission channels can increase the force transmission paths, thereby better dispersing and absorbing the vibration impact of the vehicle, which is beneficial to improving the rear collision safety performance of the vehicle, thereby improving the stability of the vehicle.

[0057] In some embodiments, the vehicle rear structure 100 further includes a rear floor front cross beam 12 , which is connected between two sets of rear floor longitudinal beams 1 , and a rear seat longitudinal beam 13 is connected between the rear floor front cross beam 12 and the shelf front cross beam 9 .

In this way, the seat back can be firmly connected to the floor and the shelf, thereby enhancing the stability of the seat. The setting of the rear seat longitudinal beam 13 also enhances the installation strength of the shelf front cross beam 9.

[0059] And / or, it also includes a rear floor middle cross beam 14, which is connected between the two groups of rear floor longitudinal beams 1, and the rear floor middle cross beam 14 is located at the bottom of the second wheel house support beam 11.

[0060] Specifically, Figure 6 and Figure 7 As shown, a rear floor middle cross beam 14 is also connected between the two groups of rear floor longitudinal beams 1, and the rear floor front cross beam 12 and the rear floor middle cross beam 14 are connected between the two groups of rear floor longitudinal beams 1 at a certain distance in the front-to-rear direction. Therefore, the rear floor front cross beam 12, the two groups of rear floor longitudinal beams 1 and the rear floor middle cross beam 14 together constitute a bottom annular reinforcement structure, which can improve the overall rigidity of the bottom of the vehicle, so that a stable frame structure can be formed at the bottom of the vehicle. When the vehicle is driving, it can better withstand road impact and vibration and reduce deformation of the vehicle body. At the same time, the enhanced bottom annular reinforcement structure can reduce the generation and transmission of noise and improve ride comfort.

[0061] The rear floor middle cross beam 14 is located at the bottom of the second wheel house support beam 11, so that the rear floor middle cross beam 14, the shelf front cross beam 9 and the two second wheel house support beams 11 can form a rear annular reinforcement structure together, further enhancing the installation strength of the shelf front cross beam 9 and improving the rear rigidity of the vehicle.

[0062] In some embodiments, the rear structure 100 of the vehicle also includes a shock absorber support 15 and a shock absorber support beam 16, the shock absorber support 15 is connected to the front side of the first wheel arch support beam 10, and the shock absorber support 15 is respectively connected to the wheel arch upper side beam 3 and the rear floor longitudinal beam 1, the upper end of the shock absorber support beam 16 is connected to the first wheel arch support beam 10 and the lower end is supported by the shock absorber support 15.

[0063] Specifically, the shock absorber support 15 is used to support and install the shock absorber, and the shock absorber support beam 16 is used to support and fix the shock absorber support 15, thereby improving the installation strength and stability of the shock absorber support 15, thereby ensuring that the shock absorber can remain in a fixed position when subjected to impact or vibration. Fig. 9As shown, the shock absorber support 15 is constructed in a bent type, with its rear side connected to the front side of the first wheel house support beam 10, its upper side connected to the wheel house upper side beam 3, and its lower side connected to the upper side of the rear floor longitudinal beam 1, so that the shock absorber support 15 is stably connected between the wheel house upper side beam 3 and the rear floor longitudinal beam 1, ensuring the installation stability of the shock absorber support 15, and the shock absorber support beam 16 is installed above the shock absorber support 15 and extends obliquely in the vertical direction, and its upper end extends to the connection On the front side of the first wheel house support beam 10, its lower end extends to be connected to the shock absorber support 15 and is spaced a certain distance from the lower end of the first wheel house support beam 10, so that the force applied to the shock absorber support 15 can be transmitted to the front cross beam 9 of the shelf through the shock absorber support beam 16, and the force applied to the subframe and the shock absorber spring mounting point on the rear floor longitudinal beam 1 can be transmitted upward, thereby reducing the force borne by the shock absorber support 15, improving its strength and stability, and thus ensuring that the shock absorber can work effectively.

[0064] At the same time, the shock absorber support 15 , the shock absorber support beam 16 , the shelf front cross beam 9 and the rear floor front cross beam 12 can jointly form a front annular reinforcement structure to enhance the strength and rigidity of the vehicle rear structure 100 .

[0065] In some embodiments, the shock absorber support 15 is provided with a support step 151 , and the lower end of the shock absorber support beam 16 is supported on the support step 151 .

[0066] Specifically, Fig. 9 and Fig.10 As shown, an inwardly protruding support step 151 is provided at the middle position of the shock absorber support 15. In practice, the lower end support of the shock absorber support beam 16 is connected to the support step 151 to support and fix the shock absorber support beam 16, thereby improving the installation stability of the shock absorber support beam 16.

[0067] And / or, the shock absorber support 15 is further provided with a plurality of reinforcing ribs 152 , which are spaced apart and distributed below the shock absorber support beam 16 , and an extension direction of at least one of the reinforcing ribs 152 is the same as an extension direction of the shock absorber support beam 16 .

[0068] Specifically, a plurality of reinforcing ribs 152 are provided to support the rear floor longitudinal beam 1, so as to improve the strength and stability of the shock absorber support 15, so as to ensure that the shock absorber can be stably supported and fixed. Fig.10As shown, five spaced-apart reinforcing ribs 152 are arranged below the shock absorber support 15, the lower ends of the reinforcing ribs 152 are connected to the rear floor longitudinal beam 1, and the reinforcing ribs 152 are distributed below the shock absorber support beam 16 to avoid interference with the support step 151. At the same time, multiple reinforcing ribs 152 are arranged to evenly disperse the borne force to improve the stability of the shock absorber support 15. The extension direction of one of the reinforcing ribs 152 is the same as the extension direction of the shock absorber support beam 16, so that the force on the shock absorber support 15 can be transmitted to the front cross beam 9 of the shelf along the support step 151 through the shock absorber support beam 16.

[0069] It should be noted that the number of the reinforcing ribs 152 is not limited to that shown in this embodiment, and can be flexibly adjusted according to actual needs. It can be understood that the more the number of reinforcing ribs 152 is set, the stronger the shock absorber support 15 is.

[0070] In some embodiments, the vehicle rear structure 100 also includes a shelf rear cross beam 17, both ends of which are connected to two sets of side edge beams 6.

The shelf rear cross beam 17 is located behind the shelf front cross beam 9 and two reinforcing longitudinal beams 18 extending forward and backward are connected therebetween. The reinforcing longitudinal beams 18 can increase the connection strength between the shelf front cross beam 9 and the shelf rear cross beam 17, so that the shelf can be stably installed thereon. At the same time, the shelf rear cross beam 17 is supported and connected between the two groups of side panel beams 6, which can enhance the strength and stability of the two groups of side panel beams 6.

[0072] In some embodiments, the vehicle rear structure 100 further includes a trunk rear cross beam 19, which is connected between two sets of wheel house rear support beams 5. Figure 6 As shown, the trunk rear cross beam 19 is located at the lower rear position of the shelf board rear cross beam 17, and its left and right ends are connected between the two sets of wheel house rear support beams 5. Therefore, the shelf board rear cross beam 17, the trunk rear cross beam 19, the two sets of wheel house rear support beams 5 and the two sets of side edge beams 6 can jointly form a central annular reinforcement structure, further enhancing the strength and rigidity of the vehicle rear structure 100 and improving the vehicle torsional rigidity.

[0073] And / or, it also includes a roof rear cross beam 20, which is connected between the two groups of side wall beams 6.

[0074] like Figure 5 and Figure 6As shown, the vehicle rear structure 100 further includes a roof rear cross beam 20, which is connected to the front of the shelf rear cross beam 17 and the left and right ends are respectively connected to the two sets of side wall beams 6, which can further enhance the strength and stability of the two sets of side wall beams 6. The arrangement of the roof rear cross beam 20 allows the roof rear cross beam 20, the shelf rear cross beam 17 and the two sets of side wall beams 6 to form an upper annular reinforcement structure, further enhancing the strength and rigidity of the vehicle rear structure 100 and improving the torsional rigidity of the vehicle.

[0075] As well as Figure 7 As shown, the vehicle rear structure 100 may also be provided with a rear floor rear cross beam 21, which is connected between the two groups of rear floor longitudinal beams 1 and is located below the rear cross beam 19 of the trunk. Thus, the rear floor rear cross beam 21, the rear cross beam 19 of the trunk, the two groups of wheel house rear support beams 5 and the two groups of rear floor longitudinal beams 1 may form a lower annular reinforcement structure, further enhancing the strength and rigidity of the vehicle rear structure 100 and improving the torsional rigidity of the vehicle. In addition, the rear floor rear cross beam 21, the rear floor middle cross beam 14 and the two groups of rear floor rear cross beams 21 may also form a bottom annular reinforcement structure.

[0076] Thus, a multi-annular reinforcement structure can be formed by connecting the upper annular reinforcement structure, the middle annular reinforcement structure and the lower annular reinforcement structure together. The multiple annular reinforcement structures can reinforce each other, greatly enhancing the rigidity and strength of the vehicle rear structure 100, improving the vehicle's torsional rigidity, thereby improving vehicle performance and allowing the vehicle to move forward smoothly.

[0077] The utility model also provides a vehicle.

[0078] According to the vehicle of the embodiment of the utility model, a vehicle rear structure 100 in any of the above embodiments is provided. Among them, the lower annular structure formed by the wheel house upper side beam 3, the wheel house front support beam 4, the wheel house rear support beam 5, the front section 2 of the rear floor longitudinal beam and the rear floor longitudinal beam 1, and the upper annular structure formed by the side wall side beam 6, the C-pillar reinforcement beam 7 and the wheel house upper side beam 3 can improve the rigidity, strength and torsional rigidity of the rear part of the vehicle, so that the vehicle can effectively resist the impact and vibration from the road surface, reduce the deformation and damage of the vehicle body, and through the arrangement of each beam, multiple force transmission paths can be provided, thereby improving the support force transmission effect and the rear collision safety performance, and multiple annular reinforcement structures can jointly improve the strength and stability of the vehicle rear structure 100.
