In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0035] In related technologies, the rear vehicle frame has numerous parts, numbering in the dozens. It mainly includes a crossbeam and two opposing side inner panels. The side inner panels mainly include the C-pillar inner panel, the D-pillar inner panel, and a connecting plate. The connecting plate connects the C-pillar inner panel and the D-pillar inner panel. The crossbeam connects the two side inner panels at the junction of the D-pillar inner panel and the connecting plate. Each part needs to be welded separately when it is fixed to each other. Due to the complexity of the welding process, it is impossible to guarantee the welding quality, which can easily affect the structural stability and strength of the rear vehicle frame.

[0036] Please see Figure 1 and Figure 2 In view of this, the present invention provides a rear vehicle frame 100, which can improve the structural stability and structural strength of the rear vehicle frame 100.

[0037] The rear vehicle frame 100 includes two rear side panel inner panels 10, a rear crossbeam 20, and at least one reinforcing beam 30. The two rear side panel inner panels 10 are arranged opposite to each other. The two ends of the rear crossbeam 20 are respectively connected to the top of the two rear side panel inner panels 10 and are located at the rear of the two rear side panel inner panels 10. The two ends of the at least one reinforcing beam 30 are respectively connected to the top of the two rear side panel inner panels 10 and are spaced apart from the rear crossbeam 20. The two rear side panel inner panels 10, the rear crossbeam 20, and the at least one reinforcing beam 30 are integrally formed structures.

[0038] In this embodiment of the invention, by integrally forming the two rear side inner panels 10, the rear crossbeam 20, and at least one reinforcing beam 30, the various parts of the rear vehicle frame 100 can be integrated into a single structure. Compared to the welding method, this embodiment eliminates the need for complex welding of the various parts of the rear vehicle frame 100, resulting in fewer production steps, higher productivity, and avoiding quality problems such as welding dimensional inaccuracies and weld defects (such as cracks and porosity) that occur during welding. Furthermore, the structural transition at the connection points between the various parts of the integrally formed rear vehicle frame 100 is smoother, with better connection strength and load-bearing performance. This effectively prevents the vehicle frame 100 from easily deforming, improves the structural stability and strength of the rear vehicle frame 100, as well as its torsional stiffness, and thus enhances the vehicle's safety performance.

[0039] In addition, by adding at least one reinforcing beam 30 to the top of the two rear side inner panels 10, when an external force is applied to the rear side inner panel 10, the external force can be transmitted to the reinforcing beam 30. The reinforcing beam 30 can be subjected to lateral force and torsional force between the two rear side inner panels 10, which optimizes the stress structure of the top of the rear body frame 100, making the structural stability and structural strength of the rear body frame 100 better and the torsional stiffness higher.

[0040] It is worth noting that, especially when the two rear side inner panels 10 of the rear body frame 100 are asymmetrical, the structure of the rear body frame 100 becomes more complex. If the two rear side inner panels 10 of the rear body frame 100 are fixed by welding, then when manufacturing the two rear side inner panels 10 of the rear body frame 100, it is necessary to manufacture two rear side inner panels 10 separately and use at least two different sets of molds, with at least one set of molds used to produce one rear side inner panel 10 and at least another set of molds used to produce the other rear side inner panel 10. However, this embodiment of the utility model, by adopting an integrated molding structure design, can reduce the number of molds required. The rear body frame 100 can be manufactured using only one set of molds, saving costs and increasing efficiency.

[0041] In the specific implementation process, the rear body frame 100 can be manufactured by die casting, so that the rear body frame 100 is an integral die casting structure.

[0042] In some embodiments, each rear side panel 10 includes a front pillar inner panel 11, a rear pillar inner panel 12, an upper connecting plate 13, and a lower connecting plate 14. The front pillar inner panel 11 and the rear pillar inner panel 12 are spaced apart. The two ends of the upper connecting plate 13 are respectively connected to the front pillar inner panel 11 and the rear pillar inner panel 12, and the two ends of the lower connecting plate 14 are respectively connected to the front pillar inner panel 11 and the rear pillar inner panel 12. The upper connecting plate 13 and the lower connecting plate 14 are spaced apart, so that the front pillar inner panel 11, the rear pillar inner panel 12, the upper connecting plate 13, and the lower connecting plate 14 can be connected to form a closed loop structure, and the two rear side panel inner panels 10 can form two closed loop structures.

[0043] Among them, the inner panel 11 of the front pillar is the inner panel of the C pillar, and the inner panel 12 of the rear pillar is the inner panel of the D pillar.

[0044] The two ends of the rear crossbeam 20 are respectively connected to the connection points of the rear support inner plate 12 and the upper connecting plate 13 of the two rear side inner panels 10. That is, one end of the rear crossbeam 20 is connected to the connection point of the rear support inner plate 12 and the upper connecting plate 13 of one rear side inner panel 10, and the other end of the rear crossbeam 20 is connected to the connection point of the rear support inner plate 12 and the upper connecting plate 13 of the other rear side inner panel 10; at least one rear crossbeam 20 is connected to the two upper connecting plates 13 of the two rear side inner panels 10. In this way, the rear crossbeam 20, the reinforcing beam 30, and the upper connecting plates 13 of the two rear side inner panels 10 can also be connected to form a closed loop structure.

[0045] In this embodiment, the rear vehicle frame 100 can be connected by multiple closed-loop structures to form a stable frame structure. When the rear vehicle frame 100 is subjected to external forces, the multiple closed-loop structures can cooperate to bear the force, which is beneficial to the transmission and dispersion of external forces in the rear vehicle frame 100. This optimizes the stress structure of the rear vehicle frame 100, resulting in better mechanical performance and improving the structural stability, structural strength, and torsional stiffness of the rear vehicle frame 100.

[0046] It is understood that a closed-loop structure refers to a closed loop formed between at least a portion of interconnected parts. The other portion of the interconnected parts can also extend outward toward the closed loop. For example, after the rear crossbeam 20, the reinforcing beam 30 and the two upper connecting plates 13 are connected to form a closed loop, the front ends of the two upper connecting plates 13 can also extend forward. The closed loop is formed by the connection of the portions of the two upper connecting plates 13 located behind the reinforcing beam 30, the reinforcing beam 30 and the rear crossbeam 20.

[0047] Specifically, in the same rear side panel 10, the front pillar inner panel 11 and the rear pillar inner panel 12 extend in the vertical direction and are arranged opposite each other and spaced apart in the front-back direction; the upper connecting plate 13 and the lower connecting plate 14 extend in the front-back direction and are arranged opposite each other and spaced apart in the vertical direction.

[0048] Two rear side inner panels 10 are arranged opposite each other and spaced apart in the left-right direction. The front pillar inner panel 11, rear pillar inner panel 12, upper connecting plate 13 and lower connecting plate 14 of one rear side inner panel 10 correspond one-to-one with the front pillar inner panel 11, rear pillar inner panel 12, upper connecting plate 13 and lower connecting plate 14 of the other rear side inner panel 10.

[0049] The rear crossbeam 20 and the reinforcing beam 30 extend in the left and right directions respectively, and are arranged opposite each other and at intervals in the front and back directions.

[0050] In some embodiments, the lower end of the front pillar inner plate 11 extends downward, or the lower end of the rear pillar inner plate 12 extends downward, or both the lower ends of the front pillar inner plate 11 and the rear pillar inner plate 12 extend downward. This arrangement causes the lower ends of the front pillar inner plate 11 and / or the rear pillar inner plate 12 to protrude downward relative to the lower connecting plate 14 by a certain length. Thus, the downward extension of the lower ends of the front pillar inner plate 11 and / or the rear pillar inner plate 12 allows them to support and connect to other structures of the vehicle, improving the structural stability of the lower ends of the front pillar inner plate 11 and / or the rear pillar inner plate 12. When external forces act on the rear vehicle frame 100, the lower ends of the front pillar inner plate 11 and / or the rear pillar inner plate 12 can provide additional stress points for the rear vehicle frame 100. External forces can be transmitted to other structures of the vehicle through the lower ends of the front pillar inner plate 11 and / or the rear pillar inner plate 12, which is beneficial for improving the structural stability, structural strength, and torsional stiffness of the rear vehicle frame 100.

[0051] In one example, the lower ends of the front pillar inner panel 11 and the rear pillar inner panel 12 of each rear side panel 10 extend downward away from the lower connecting plate 14, thereby forming a stable four-legged support at the bottom of the rear body frame 100 and connecting it to the other structure of the vehicle.

[0052] In practice, the lower ends of the front pillar inner panel 11 and / or the rear pillar inner panel 12 can be supported and connected to the rear outer panel of the vehicle.

[0053] In some embodiments, the inner plate 11 of the front pillar is provided with reinforcing ribs 40, which extend along the direction from the upper connecting plate 13 to the lower connecting plate 14, that is, the reinforcing ribs 40 on the inner plate 11 of the front pillar extend in the vertical direction; and / or, the inner plate 12 of the rear pillar is provided with reinforcing ribs 40, which extend along the direction from the upper connecting plate 13 to the lower connecting plate 14, that is, the reinforcing ribs 40 on the inner plate 12 of the rear pillar extend in the vertical direction; and / or, the upper connecting plate 13 is provided with reinforcing ribs 40, which extend along the direction from the inner plate 11 of the front pillar to the lower connecting plate 14. The inner plate 12 of the support column extends in a certain direction, that is, the reinforcing rib 40 on the upper connecting plate 13 extends in the front-rear direction; and / or, the lower connecting plate 14 is provided with a reinforcing rib 40, which extends in the direction from the inner plate 11 of the front support column to the inner plate 12 of the rear support column, that is, the reinforcing rib 40 on the lower connecting plate 14 extends in the front-rear direction; and / or, the rear crossbeam 20 is provided with a reinforcing rib 40, which extends in the direction from one rear side inner plate 10 to the other rear side inner plate 10, that is, the reinforcing rib 40 of the rear crossbeam 20 extends in the left-right direction.

[0054] In this embodiment, by setting the reinforcing rib 40, the deformation resistance of the corresponding part can be effectively increased. When a vehicle collision occurs, the energy can be dispersed to the reinforcing rib 40, so that the impact force can be transmitted along the extension path of the reinforcing rib 40, avoiding the energy from concentrating in a certain place and causing local deformation, thereby improving the structural stability, structural strength, and torsional stiffness of the part.

[0055] Among them, the reinforcing rib 40, the rear side inner plate 10, the rear crossbeam 20 and at least one reinforcing beam 30 are integrally formed structures.

[0056] In one example, the front pillar inner plate 11, the rear pillar inner plate 12, the upper connecting plate 13, the lower connecting plate 14, and the rear crossbeam 20 are all provided with reinforcing ribs 40, thereby improving the overall structural stability and strength of the rear vehicle frame 100, as well as its torsional stiffness.

[0057] In some embodiments, the reinforcing rib 40 includes a first sub-reinforcing rib 41 and a second sub-reinforcing rib 42, which are intersecting. Through this arrangement, the first sub-reinforcing rib 41 and the second sub-reinforcing rib 42 can be crisscrossed and connected, allowing external forces acting on them to be transmitted in different directions. This enables the reinforcing rib 40 to effectively resist external forces, promotes more uniform stress distribution, and reduces the likelihood of part deformation.

[0058] It is understandable that the intersection method of the first sub-reinforcing rib 41 and the second sub-reinforcing rib 42 can be set according to actual needs, for example, as... Figure 2As shown, in the upper connecting plate 13, the first sub-reinforcing rib 41 extends in a straight line from the front end of the upper connecting plate 13 to the rear end of the upper connecting plate 13, and a plurality of second sub-reinforcing ribs 42 are spaced apart in the front-rear direction and intersect the first sub-reinforcing rib 41 perpendicularly. For example, in the rear support inner plate 12, the first sub-reinforcing rib 41 extends in a zigzag line from the upper end of the rear support inner plate 12 to the lower end of the rear support inner plate 12, and a plurality of second sub-reinforcing ribs 42 are spaced apart in the up-down direction and intersect the first sub-reinforcing rib 41 at an angle, which is an acute angle or an obtuse angle.

[0059] In some embodiments, the reinforcing rib 40 further includes a reinforcing column 43, which is connected to the intersection of the first sub-reinforcing rib 41 and the second sub-reinforcing rib 42. The diameter of the reinforcing column 43 is greater than the thickness of the first sub-reinforcing rib 41 and the second sub-reinforcing rib 42. This can improve the connection strength at the intersection of the first sub-reinforcing rib 41 and the second sub-reinforcing rib 42, so that the first sub-reinforcing rib 41 and the second sub-reinforcing rib 42 can withstand a larger shear force, and prevent the intersection of the first sub-reinforcing rib 41 and the second sub-reinforcing rib 42 from breaking under the impact of external force, thereby making the reinforcing rib 40 more effective in resisting external force.

[0060] Typically, the rear side inner panel 10 is designed with a window. The window will cause the middle of the rear side inner panel 10 to be hollowed out, resulting in the upper structure of the window of the rear side inner panel 10 not being able to obtain support from the window, and its structural strength is relatively weak.

[0061] Therefore, in some embodiments, the two rear inner panels 10 respectively define windows 101, and at least one reinforcing beam 30 is located on the upper side between the windows 101 of the two rear inner panels 10. That is, at least one reinforcing beam 30 is located above the space between the windows 101 of the two rear inner panels 10. In this way, the reinforcing beam 30 can simultaneously support the upper structure of the windows 101 of the two rear inner panels 10. When the upper structure of the windows 101 of the rear inner panels 10 is subjected to external force, the upper structure of the windows 101 of the rear inner panels 10 can transfer stress to the reinforcing beam 30, thereby preventing the upper structure of the windows 101 from easily deforming under stress and improving the structural strength of the upper structure of the windows 101 of the rear inner panels 10.

[0062] The window 101 is defined by the front column inner plate 11, the rear column inner plate 12, the upper connecting plate 13, and the lower connecting plate 14. The structure above the window 101 of the rear side inner plate 10 is the structure in which the upper connecting plate 13 is located between the front column inner plate 11 and the rear column inner plate 12. The reinforcing beam 30 is the structure that connects the upper connecting plate 13 in the middle of the front column inner plate 11 and the rear column inner plate 12.

[0063] In some embodiments, the number of reinforcing beams 30 is at least two, and the two ends of the at least two reinforcing beams 30 are respectively connected to the top of the two rear side inner panels 10. The at least two reinforcing beams 30 are spaced apart, so that the rear crossbeam 20, the at least two reinforcing beams 30, and the upper connecting plates 13 of the two rear side inner panels 10 can be connected to form multiple closed-loop structures. For example, the two reinforcing beams 30 and the upper connecting plates 13 of the two rear side inner panels 10 can be connected to form one closed-loop structure, and one reinforcing beam 30, the rear crossbeam 20, and the upper connecting plates 13 of the two rear side inner panels 10 can be connected to form another closed-loop structure.

[0064] In this embodiment, the top of the rear body frame 100 can be connected by multiple closed-loop structures to form a stable frame structure. When an external force is applied to the rear side inner panel 10, the external force can be transmitted and dispersed to different reinforcing beams 30. Each reinforcing beam 30 can be subjected to lateral force and torsional force between the two rear side inner panels 10, which is more conducive to the transmission and dispersion of external force in the rear body frame 100. This further optimizes the stress structure of the rear body frame 100, improves its mechanical properties, and further enhances the structural stability, structural strength, and torsional stiffness of the rear body frame 100.

[0065] In one example, there are two reinforcing beams 30, which are spaced apart in the front-to-back direction and are both located on the upper side between the windows 101 of the two rear inner panels 10.

[0066] Typically, the rear body frame 100 uses a steel frame or an aluminum alloy frame, resulting in a large overall weight of the rear body frame 100, which cannot meet the requirements for lightweighting and weight reduction of the vehicle body.

[0067] In view of this, in some embodiments, the rear vehicle frame 100 is a magnesium alloy frame. By using a magnesium alloy frame, its weight is lighter (approximately 30% lighter than an aluminum alloy frame and 50% lighter than a steel frame), which can meet the requirements for lightweighting and weight reduction of the vehicle body.

[0068] In addition, although magnesium alloy skeletons have low density, they have high specific strength (strength to density ratio). Under the same rigidity conditions, magnesium alloys are stronger than aluminum alloys. Furthermore, magnesium alloy skeletons have good vibration absorption properties, which can effectively absorb vibrations when subjected to impact, providing passengers with a more comfortable riding experience.

[0069] This utility model embodiment also provides a vehicle, which includes the rear body frame 100 as described above.

[0070] The vehicle of this utility model embodiment has the beneficial effects of the rear body frame 100, which will not be described in detail here.

[0071] It should be noted that the vehicle referred to in this embodiment of the utility model can be a private car, such as a sedan, SUV, MPV, or pickup truck. The vehicle can also be a commercial vehicle, such as a van, bus, or truck. The vehicle can be a gasoline-powered vehicle or a new energy vehicle. When the vehicle is a new energy vehicle, it can be a hybrid vehicle or a pure electric vehicle.

[0072] It should be noted that the vehicle provided in this embodiment of the present invention only shows the part related to the technical problem to be solved by this embodiment of the present invention. It is understood that the vehicle provided in this embodiment of the present invention also includes other structures for realizing the function of the vehicle, including but not limited to the front body frame, etc.

[0073] Within the scope of knowledge possessed by those skilled in the art, various modifications can be made without departing from the spirit of this utility model. Furthermore, embodiments of this utility model and features thereof can be combined with each other, unless otherwise specified.
