[0002] To ensure vehicle safety, the vehicle body must possess good rigidity, particularly at the rear. The rear pillar structure is crucial for ensuring rear vehicle rigidity. The rear pillar typically consists of stamped inner and outer panels welded together to form a cavity. This cavity can be enhanced by adding reinforcement plates to the structure.

[0053] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0054] In the description of this application, it should be noted that if the terms "upper", "lower", "left", "right", "inner", "outer", etc. appear in the description, the directions or positional relationships indicated are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the product of the application is usually placed when in use. These directions or positional relationships are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting this application. In addition, if the terms "first", "second", etc. appear in the description of this application, they are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0055] It should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be interpreted broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0056] According to the first aspect of this application, referring to Figure 1 and Figure 2 As shown, the present disclosure provides a vehicle body reinforcement structure, including a shelf crossbeam 2, a first shock-absorbing beam 4, and a second shock-absorbing beam 5. The first shock-absorbing beam 4 is connected to one end of the shelf crossbeam 2, and the second shock-absorbing beam 5 is connected to the other end of the shelf crossbeam 2. The ends of the first shock-absorbing beam 4 and the second shock-absorbing beam 5, which are away from the shelf crossbeam 2, are respectively connected to the vehicle body floor 9, so that the shelf crossbeam 2, the first shock-absorbing beam 4, the second shock-absorbing beam 5, and the vehicle body floor 9 form an annular structure.

[0057] The shelf crossbeam 2 refers to a beam located above or below the shelf and used to support the shelf. For ease of viewing the shelf crossbeam 2, the shelf is hidden in the figure. It can be understood that the shelf is a plate-shaped member arranged above or below the shelf crossbeam 2 and can be used to place items.

[0058] The reinforcement structure provided by the embodiment of the present application is formed by connecting the first shock-absorbing beam 4 and the second shock-absorbing beam 5 to the two ends of the shelf crossbeam 2 to form an inverted U-shaped structure. The U-shaped structure is arranged between the shelf and the floor 9 of the vehicle body. The opening of the U-shaped structure is connected to the floor 9 of the vehicle body to form an annular structure, thereby incorporating the original floor 9 and the shelf of the vehicle body into the force system to form an annular force transmission path. The annular force transmission path can reduce the deformation of the rear part of the vehicle body, improve the anti-twisting ability of the rear part of the vehicle body, and obtain a vehicle body with high torsional rigidity. Without adding additional reinforcement parts and materials, the embodiment of the present application utilizes the existing necessary parts of the vehicle body to form an annular structure, thereby improving the rigidity and impact resistance of the rear part of the vehicle body, taking into account the rigidity requirements and lightweight requirements of the vehicle body, and optimizing the space of the entire vehicle.

[0059] In some embodiments, as Figure 1 As shown, the shelf crossbeam 2 is provided with a bearing surface 21 for supporting and connecting the shelf. By providing the bearing surface 21, the connection area between the shelf crossbeam 2 and the shelf is increased, thereby improving the stability of the shelf itself, thereby increasing the load-bearing capacity of the shelf, and also improving the connection stability between the shelf crossbeam 2 and the shelf.

[0060] In some embodiments, the first shock-absorbing beam 4 and the second shock-absorbing beam 5 can be directly connected to the shelf crossbeam 2, for example, by welding, anchoring, or gluing.

[0061] In some embodiments, as Figure 1 As shown, the reinforcement structure further includes a first connector 1 and a second connector 3. The first shock-absorbing beam 4 is connected to the shelf crossbeam 2 via the first connector 1, and the second shock-absorbing beam 5 is connected to the shelf crossbeam 2 via the second connector 3. The first connector 1 and the second connector 3 form a U-shaped corner node, thereby improving the structural rigidity.

[0062] In an embodiment including a first connecting member 1 and a second connecting member 3, the first shock-absorbing beam 4 is connected to one end of the shelf board cross beam 2 through the first connecting member 1, and the second shock-absorbing beam 5 is connected to the other end of the shelf board cross beam 2 through the second connecting member 3, so that the first shock-absorbing beam 4, the first connecting member 1, the shelf board cross beam 2, the second connecting member 3 and the second shock-absorbing beam 5 are connected in sequence to form an inverted U-shaped structure. The U-shaped structure is arranged between the floor 9 of the vehicle body and the shelf board. The opening of the U-shaped structure is connected to the floor 9 of the vehicle body to form a ring structure, and is connected to the shelf board, so that the original shelf board and floor 9 of the vehicle body are included in the force system.

[0063] Optionally, the first connecting member 1 and the second connecting member 3 provided in the embodiment of the present application are integrally formed using a cast aluminum process. The first connecting member 1 and the second connecting member 3 are light in weight, and have high strength and rigidity, which can further take into account the torsional rigidity requirements and lightweight requirements of the rear structure of the vehicle body.

[0064] Optionally, the shelf cross beam, the first shock-absorbing beam, and the second shock-absorbing beam are all made of aluminum profiles to increase the cross-sectional area of ​​the beam components and improve the torsional rigidity.

[0065] It should be noted that there are various ways to connect the first connecting member, the second connecting member, the shelf cross beam, the first shock-absorbing beam, the second shock-absorbing beam and the floor of the vehicle body, such as welding, anchor connection or gluing.

[0066] In some embodiments, the first connector, the second connector, the shelf crossbeam, the first shock-absorbing beam, the second shock-absorbing beam, the vehicle body floor, and the shelf are connected by anchors at a first torque. Anchors include bolts, screws, rivets, and the like. Tightening all anchors with a uniform torque promotes overall connection consistency and ensures a stable installation cycle.

[0067] In some embodiments, as Figure 3 and Figure 4As shown, the first connector 1 comprises a first left portion 11 and a second left portion 12, while the second connector 3 comprises a first right portion 31 and a second right portion 32. The first left portion 11 and the first right portion 31 are respectively connected to the shelf crossbeam 2. The second left portion 12 is connected to the first left portion 11 and extends downward, while the second right portion 32 is connected to the first right portion 31 and extends downward. This arrangement provides sufficient connection surface between the shelf crossbeam 2 and the two damping beams, resulting in a U-shaped structure with a high node strength.

[0068] Please see again Figure 3 As shown, the first left portion 11 includes a first left connecting portion 111, a second left connecting portion 112, and a third left connecting portion 113, which are connected in sequence. The first left connecting portion 111 and the third left connecting portion 113 are arranged opposite each other. The first left connecting portion 111 is connected to the top of the shelf crossbeam 2, the third left connecting portion 113 is connected to the bottom of the shelf crossbeam 2, and the second left connecting portion 112 is arranged between the first left connecting portion 111 and the third left connecting portion 113 and is connected to the left rear pillar of the vehicle body. By configuring the first left portion 11 to include the first left connecting portion 111, the second left connecting portion 112, and the third left connecting portion 113, the number of connection points between the connecting member and the shelf crossbeam 2 and the connection area between the connecting member and the rear pillar can be increased, thereby improving the strength of the node.

[0069] Please see again Figure 4 As shown, the first right side portion 31 includes a first right connecting portion 311, a second right connecting portion 312, and a third right connecting portion 313, which are connected in sequence. The first right connecting portion 311 and the third right connecting portion 313 are arranged opposite each other. The first right connecting portion 311 is connected to the top of the shelf crossbeam 2, the third right connecting portion 313 is connected to the bottom of the shelf crossbeam 2, and the second right connecting portion 312 is arranged between the first right connecting portion 311 and the third right connecting portion 313 and is connected to the right rear pillar of the vehicle body. By configuring the first right side portion 31 to include the first right connecting portion 311, the second right connecting portion 312, and the third right connecting portion 313, the number of connection points between the connecting member and the shelf crossbeam 2 and the connection area between the connecting member and the rear pillar can be increased, thereby improving the strength of the node.

[0070] The rear pillar is the area between the rear door and the rear window of the vehicle body. Depending on the model, the rear pillar can be either the C-pillar or the D-pillar. By connecting the ring structure between the left and right rear pillars, the rigidity of the rear part of the vehicle body can be further improved.

[0071] In some embodiments, as Figure 3 As shown, the second left connecting portion 112 is spaced apart from the left side of the shelf beam 2 to form a left stress release space 13, as shown in FIG. Figure 4As shown, the second right connecting portion 312 is spaced apart from the right side of the shelf cross beam 2 to form a right stress release space 33. In this way, by providing the stress release space, the ability to resist lateral impact can be improved.

[0072] In some embodiments, as Figure 3 and Figure 4 As shown, the first left connecting portion 111 is formed with an upwardly protruding left positioning member 114, and the first right connecting portion 311 is formed with an upwardly protruding right positioning member 314. The left positioning member 114 and the right positioning member 314 are respectively provided on the left and right sides of the shelf to position the shelf. This not only facilitates the installation and positioning of the shelf, but also increases the lateral contact area between the first connecting member 1 and the second connecting member 3 and the shelf, improving the ability to resist lateral impact.

[0073] In some embodiments, as Figure 3 and Figure 4 As shown, the first connecting member 1 is provided with a first positioning hole 14, the second connecting member 3 is provided with a second positioning hole 34, and the shelf crossbeam 2 is connected to the first positioning hole 14 and the second positioning hole 34. Anchor members such as bolts, screws, or rivets are provided at both ends of the shelf crossbeam 2 to be inserted and fixed to the first positioning hole 14 and the second positioning hole 34; alternatively, through holes are provided at both ends of the shelf crossbeam 2, and the through holes correspond to the corresponding positioning holes and are fixed with screws, bolts, or rivets.

[0074] One of the first and second positioning holes 14, 34 is a strip-shaped hole. If manufacturing tolerances exist, one end of the shelf beam 2 can be first connected to the non-strip-shaped positioning hole. The other end of the shelf beam 2 can then be adjusted relative to the strip-shaped hole before being secured by an anchor through the strip-shaped hole. By designing one of the first and second positioning holes 14, 34 as a strip-shaped hole, manufacturing precision requirements can be reduced, error tolerance can be increased, and processing difficulty and cost can be lowered.

[0075] In some embodiments, the length direction of the strip-shaped hole is along the front-rear direction of the vehicle body, so that the shelf cross beam 2 can be accurately positioned in the front-rear direction of the vehicle body.

[0076] In some embodiments, as Figure 3 and Figure 4 As shown, the first connecting member 1 is also provided with a first locking hole 15, and the second connecting member 3 is provided with a second locking hole 35. The opposite ends of the shelf beam 2 are respectively connected to the first locking hole 15 and the second locking hole 35 to further fix the shelf beam 2, improve the connection stability, and prevent the shelf beam 2 from swinging along the strip hole.

[0077] In some embodiments, the first connector 1 includes two first locking holes 15, the second connector 3 includes two second locking holes 35, the first positioning hole 14 is disposed between the two first locking holes 15, and the second positioning hole 34 is disposed between the two second locking holes 35. By disposing the positioning hole between the two locking holes, both sides of the positioning hole are connected to the shelf crossbeam 2 via anchors, resulting in relatively uniform stress on both sides and improving the fixing effect.

[0078] In some embodiments, as Figure 5 and Figure 6 As shown, the reinforcement structure of the vehicle body further includes a first mounting bracket 6 and a second mounting bracket 7. Figure 2 and Figure 5 As shown, the first mounting bracket 6 is provided on the left rear wheel housing 81 of the vehicle body, and the lower end of the first shock absorbing beam 4 is connected to the first mounting bracket 6 so as to be connected to the floor 9 of the vehicle body through the left rear wheel housing 81. Figure 2 and Figure 6 As shown, the second mounting bracket 7 is mounted on the right rear wheelhouse 82 of the vehicle body. The lower end of the second shock absorber beam 5 is connected to the second mounting bracket 7, thereby connecting to the vehicle body floor 9 through the right rear wheelhouse 82. The first mounting bracket 6 can be integrally formed with the left rear wheelhouse 81, welded to the left rear wheelhouse 81, or secured to the left rear wheelhouse 81 via anchors such as bolts, screws, or rivets. The second mounting bracket 7 can be integrally formed with the right rear wheelhouse 82, welded to the right rear wheelhouse 82, or secured to the right rear wheelhouse 82 via anchors such as bolts, screws, or rivets. Optionally, the first mounting bracket 6 is fixedly connected to the left rear wheelhouse 81 via an anchor with a first torque, while the second mounting bracket 7 is fixedly connected to the right rear wheelhouse 82 via an anchor with a second torque. The provision of the first mounting bracket 6 and the second mounting bracket 7 further incorporates the left and right rear wheelhouses 81, 82 into the load-bearing system, and the two shock absorber beams are moved outward, freeing up more interior space and improving space utilization.

[0079] In some embodiments, as Figure 5 As shown, the first mounting bracket 6 includes a first left mounting surface 61, a second left mounting surface 62 and a third left mounting surface 63, which are sequentially connected and arranged around the side of the first shock absorbing beam 4 and connected to the first shock absorbing beam 4. Figure 6 As shown, the second mounting bracket 7 includes a first right mounting surface 71, a second right mounting surface 72, and a third right mounting surface 73. The first right mounting surface 71, the second right mounting surface 72, and the third right mounting surface 73 are sequentially connected and arranged around the side of the second shock-absorbing beam 5 and connected to the second shock-absorbing beam 5. The six surfaces of the two brackets cooperate to improve the restraint in the front, back, left, and right directions, and enhance the connection stability.

[0080] According to a second aspect of the present application, a vehicle body is provided, such as Figure 1 and Figure 2 As shown, the vehicle body includes a floor 9, a storage board, a rear pillar, and a reinforcement structure provided by any one of the embodiments of the first aspect. The reinforcement structure is connected to the floor 9 to form an annular structure, which is connected between the two rear pillars and connected to the storage board.

[0081] Optionally, the annular structure can be connected to the rear pillar, floor, or shelf by various methods, such as welding, anchoring, or gluing. In some embodiments, the annular structure is connected to the rear pillar, floor, or shelf with a first torque via anchors, such as bolts, screws, or rivets.

[0082] According to a third aspect of the present application, a vehicle is provided, comprising the vehicle body of the second aspect.

[0083] The vehicle may be a fuel vehicle, a plug-in hybrid vehicle, a new energy vehicle, etc., and this disclosure does not make any specific limitations on this.

[0084] The reinforcement structure provided by the embodiment of the present application transmits the force along the annular structure when the vehicle body is subjected to a side impact force. Figure 2 As shown, taking the example of a side impact force from the right side of the vehicle body, the side impact force is transmitted along the annular structure, for example: the force-bearing surface a2 of the second connecting member 3 → the force-bearing surface b of the shelf crossbeam 2 → the force-bearing surface a1 of the first connecting member 1 → the force-bearing surface c1 of the first shock-absorbing beam 4 → the force-bearing surface d1 of the first mounting bracket 6 → the frame of the floor 9 → the force-bearing surface d2 of the second mounting bracket 7 → the force-bearing surface c2 of the second shock-absorbing beam 5 → the force-bearing surface a of the second connecting member 3. This annular force transmission path reduces vehicle body deformation and improves the vehicle's torsional resistance, thereby enhancing its driving stability. Due to the vehicle's high torsional rigidity, the vehicle body is less susceptible to deformation, resulting in minimal deformation during collisions, high defensive capabilities, excellent safety, and low vibration and noise.

[0085] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more features.
