Description

Technical Field

[0001] This application relates to the field of vehicle body technology, and particularly to a rear body structure. This application also relates to a vehicle using this rear body structure. Background Technology

[0002] The tailgates on existing vehicles, classified by their opening method, typically include lift-up tailgates and side-opening tailgates.

[0003] Traditional side-opening tailgates are mounted on pillars at the rear of the vehicle via tailgate hinges. Specifically, the hinge mounting points on the pillars typically employ single or double-layer sheet metal structures. Side-opening tailgate structures generally include tailgate suspension or rear storage compartments. The overall weight of the tailgate results in significant stress on the hinge mounting points on the pillars, and these points are subjected to shear forces over time, leading to a substantial risk of pillar deformation. Utility Model Content

[0004] In view of this, this application aims to propose a rear structure for a vehicle body to improve the structural strength and rigidity of the hinge mounting area.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A rear structure of a vehicle body includes a pillar, a tailgate hinge mounted on the pillar, and a support member disposed within the pillar. The column includes an inner plate and an outer plate that enclose the receiving cavity, a column reinforcing plate and a hinge mounting reinforcing plate disposed within the receiving cavity; The support member is located between the column reinforcing plate and the hinge mounting reinforcing plate. The front end of the support member is connected to a first connector that passes through the inner plate of the column and the column reinforcing plate. The rear end of the support member is connected to a second connector that passes through the rear door hinge, the outer plate of the column, and the hinge mounting reinforcing plate.

[0006] Furthermore, the receiving cavity includes a first receiving cavity and a second receiving cavity, which are located on the front and rear sides of the column reinforcing plate, respectively.

[0007] Furthermore, the pillar reinforcement plate has a protruding portion that protrudes forward along the vehicle's front-rear direction, the protruding portion being fitted and connected to the inner plate of the pillar, and the first connector passing through the protruding portion; and / or, the hinge mounting reinforcement plate is fitted and connected to the front side of the outer plate of the pillar.

[0008] Furthermore, the tailgate hinge includes an upper tailgate hinge and a lower tailgate hinge, which are arranged at intervals in the vertical direction of the vehicle. The support includes an upper support corresponding to the upper hinge of the tailgate and a lower support corresponding to the lower hinge of the tailgate, the upper support and the lower support being spaced apart in the vertical direction of the vehicle.

[0009] Furthermore, the front ends of both the upper support and the lower support are fitted with first sleeves, and the first connecting members correspond one-to-one with the first sleeves. Each first connecting member includes a bolt that is screwed to the corresponding first sleeve.

[0010] Furthermore, the upper support member includes an upper support plate and a first upper support column integrally formed with the upper support plate; The first connector and the second connector connected to the upper support member are respectively provided with the first upper support column. Each of the first upper support columns extends along the front-rear direction of the vehicle, and both ends of each of the first upper support columns are respectively connected to the corresponding first connector and the second connector.

[0011] Furthermore, the lower support member includes a lower support plate, and a first lower support column and a second lower support column integrally formed with the lower support plate; the first lower support column and the second lower support column are arranged in a staggered manner. The first connecting member connected to the lower support member is correspondingly provided with the first lower support column, and the first lower support column is connected to the corresponding first connecting member; The second connecting member connected to the lower support member is correspondingly provided with the second lower support column, and the second lower support column is connected to the corresponding second connecting member.

[0012] Furthermore, along the longitudinal direction of the vehicle, at least one of the front and rear sides of the upper support member is provided with a first reinforcing rib; and / or, Along the longitudinal direction of the vehicle, at least one of the front and rear sides of the lower support member is provided with a second reinforcing rib.

[0013] Furthermore, both the upper support and the lower support are formed using a die-casting process.

[0014] Compared with related technologies, this application has the following advantages: (1) The rear structure of the vehicle body described in this application, by setting a pillar reinforcement plate and a hinge mounting reinforcement plate inside the pillar, and at the same time, the support member is located between the pillar reinforcement plate and the hinge mounting reinforcement plate, the support member can form a stable support structure between the pillar reinforcement plate and the hinge mounting reinforcement plate. The pillar reinforcement plate and the hinge mounting reinforcement plate can effectively improve the structural strength and rigidity of the pillar. The front end of the support member is connected to the first connecting member passing through the inner plate of the pillar and the pillar reinforcement plate, and the rear end of the support member is connected to the second connecting member passing through the tailgate hinge, the outer plate of the pillar and the hinge mounting reinforcement plate. This can effectively improve the structural strength and rigidity of the hinge mounting point and reduce the risk of pillar deformation.

[0015] The support component itself has good resistance to deformation. The support component forms a continuous support structure in the front and rear directions of the vehicle. The three-layer structure combination of the front side of the pillar (inner pillar plate and pillar reinforcement plate), the support component and the rear side of the pillar (outer pillar plate and hinge mounting reinforcement plate) can effectively improve the strength and rigidity of the rear structure of the vehicle body. Under the condition of being subjected to a large force at the hinge of the side-opening rear door, the above structure can effectively prevent the pillar from deforming, thereby improving the safety and reliability of the vehicle application.

[0016] (2) The arrangement of the first and second accommodating cavities in front and behind can significantly improve the vertical bending resistance of the column, thereby improving the load-bearing capacity of the column.

[0017] (3) The protruding part is fitted and connected to the inner plate of the column, so that the support can completely penetrate from the rear side wall of the column to the front side wall of the column, which can effectively prevent the deformation of the inner plate of the column. The hinge mounting reinforcement plate is fitted and connected to the front side of the outer plate of the column, which can effectively improve the tensile and shear resistance of the hinge mounting point on the outer plate of the column, thereby effectively preventing the deformation of the outer plate of the column.

[0018] (4) Set up the upper hinge and the lower hinge of the tailgate respectively, and set up the corresponding upper support and lower support. This will enable the tailgate to have two connection areas with the vehicle body, with better connection strength, and form two opposite force transmission paths, thereby improving the load-bearing capacity of the tailgate.

[0019] (5) A first sleeve is installed in the upper support and the lower support. The support can be made of a lighter material, and the first sleeve can be made of a higher strength material. The first sleeve is responsible for connecting with the first fastener, which is beneficial to take into account the lightweight design of the vehicle body and the structural reinforcement effect of the pillar.

[0020] (6) The upper support plate and the first upper support column are integrally formed, which can significantly improve the overall structural strength of the upper support component. The first upper support column extends along the front-rear direction of the vehicle, and its two ends are connected to the corresponding first connector and second connector respectively, so that the first upper support column can provide stable support force in the front-rear direction of the vehicle, effectively disperse and transmit the load from other vehicle components such as the first connector and the second connector, and further enhance the local strength and stability of the entire support structure.

[0021] (7) The first lower support column, the second lower support column and the lower support plate are designed as an integral part, which makes the lower support component have high structural strength. The staggered arrangement of the first lower support column and the second lower support column can make the arrangement position of the lower support component more flexible and easy to adapt to the vehicle body structure. At the same time, it can also take into account the lightweight requirements of the lower support component and the strengthening effect on the column.

[0022] (8) A first reinforcing rib is provided on at least one side of the upper support member in the front-rear direction, which can strengthen the structural strength of the upper support member. A second reinforcing rib is provided on at least one side of the lower support member in the front-rear direction, which can strengthen the structural strength of the lower support member. These reinforcing ribs have a stress-dispersing effect and enable the upper and lower support members to obtain higher load-bearing capacity with less material, which is beneficial to the lightweight design of the vehicle body.

[0023] (9) The use of die casting process can greatly improve production efficiency. Die casting molds have high precision and stability, which can ensure the dimensional and shape accuracy of the upper and lower support parts. The dimensional deviation of the molded parts is small and the interchangeability is good, which is beneficial to the subsequent assembly work.

[0024] Another object of this application is to provide a vehicle having the rear body structure described above.

[0025] The vehicle described in this application, by applying the aforementioned rear body structure, can effectively improve the structural strength and rigidity of the hinge mounting point, as well as the strength and rigidity of the rear body structure. Under the condition of being subjected to a large force at the side-opening tailgate hinge, the aforementioned rear body structure can effectively prevent the pillar from deforming, thereby improving the safety and reliability of the vehicle application.

[0035] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0036] An embodiment of the first aspect of this application provides a vehicle rear structure, and particularly relates to a vehicle rear structure capable of installing a side-opening tailgate. This vehicle rear structure has good structural strength and rigidity, thereby having a large load-bearing capacity and a small risk of deformation.

[0037] In related technologies, based on the opening method, the tailgate of a vehicle typically includes lift-up tailgates and side-opening tailgates. Lift-up tailgates are generally fixed to the roof of the vehicle via tailgate hinges and open upwards, while traditional side-opening tailgates are generally mounted on a pillar at the rear of the vehicle via tailgate hinges.

[0038] Existing side-opening tailgates typically use single- or double-layer sheet metal structures for the hinge mounting points on the pillars. Side-opening tailgate structures generally include tailgate suspension or rear storage compartments, resulting in a heavy overall weight. This causes significant stress on the hinge mounting points on the pillars, and the long-term exposure to shear forces at these points increases the risk of pillar deformation.

[0039] To ensure that the hinge mounting area has sufficient strength to support the side-opening tailgate, the common method is to increase the material thickness in these areas to improve structural strength. This results in a larger vehicle weight, which is not conducive to the lightweight design of the vehicle.

[0040] In view of this, in order to overcome the shortcomings of the related technology, the rear structure of the vehicle body in this embodiment combines... Figures 1 to 3 As shown, the overall design includes a column 1, a rear door hinge 2 installed on the column 1, and a support member 3 located inside the column 1.

[0041] Based on the above general introduction, specifically, the column 1 includes an inner plate 101 and an outer plate 102 that enclose the receiving cavity 10a, a column reinforcing plate 103 and a hinge mounting reinforcing plate 104 disposed in the receiving cavity 10a. The support member 3 is located between the column reinforcing plate 103 and the hinge mounting reinforcing plate 104. The front end of the support member 3 is connected to the first connecting member 4 that passes through the inner plate 101 of the column and the column reinforcing plate 103. The rear end of the support member 3 is connected to the second connecting member 5 that passes through the rear door hinge 2, the outer plate 102 of the column and the hinge mounting reinforcing plate 104.

[0042] It should be noted that the pillar 1 in this embodiment can be, for example, the D-pillar at the rear of the vehicle body. The following description will use the example of pillar 1 being the D-pillar.

[0043] The rear structure of the vehicle body described in this application can effectively improve the structural strength and rigidity of the pillar 1 by providing a pillar reinforcement plate 103 and a hinge mounting reinforcement plate 104 inside the pillar 1. A support member 3 is provided between the pillar reinforcement plate 103 and the hinge mounting reinforcement plate 104, and the support member 3 can form a stable support structure between the pillar reinforcement plate 103 and the hinge mounting reinforcement plate 104.

[0044] The front end of the support member 3 is connected to the first connector 4 that passes through the inner plate 101 of the column and the column reinforcing plate 103, and the rear end of the support member 3 is connected to the second connector 5 that passes through the rear door hinge 2, the outer plate 102 of the column and the hinge mounting reinforcing plate 104. This allows the two ends of the support member 3 to abut against the front side (inner plate 101 of the column and column reinforcing plate 103) and the rear side (outer plate 102 of the column and hinge mounting reinforcing plate 104) of the column 1, respectively. This forms a stable support structure between the front and rear sides of the column 1, effectively improving the structural strength and rigidity of the hinge mounting point.

[0045] In addition, the support member 3 itself has good resistance to deformation. The support member 3 forms a continuous support structure in the front and rear directions of the vehicle. The combination of the three-layer structure of the front side of the pillar 1, the support member 3 and the rear side of the pillar 1 can effectively improve the strength and rigidity of the rear structure of the vehicle body. Under the condition of a large force at the side-opening rear tailgate hinge 2, the above structure can effectively prevent the pillar 1 from deforming, thereby improving the safety and reliability of the vehicle application.

[0046] In the automotive body structure, pillars such as the D-pillar are key components connecting the roof, side panels, and rear panel. Their structural design directly affects the rigidity, strength, collision safety, and functional integration of the vehicle body.

[0047] In the above embodiment, the inner column panel 101 and the outer column panel 102 are arranged front-to-back along the vehicle's longitudinal direction, and both extend along the vehicle's vertical direction. The inner column panel 101 and the outer column panel 102 enclose a receiving cavity 10a. This creates a receiving cavity 10a extending along the vehicle's vertical direction within the column 1. This hollow structure effectively improves the bending and torsional stiffness of the column 1, while also providing installation space for internal reinforcing components such as the column reinforcing plate 103 and the hinge mounting reinforcing plate 104. It should be noted that the column reinforcing plate 103 and the hinge mounting reinforcing plate 104 also extend along the vehicle's vertical direction.

[0048] Meanwhile, the hollow structure is lighter than the solid structure, which aligns with the trend of lightweight design. The cavity 10a can also block the sound and vibration transmission path, improving NVH (Noise, Vibration, Harshness) performance.

[0049] The pillar reinforcement plate 103 enhances the overall rigidity of the pillar 1, effectively improving its impact resistance and preventing vehicle body deformation from intruding into the passenger compartment. The hinge mounting reinforcement plate 104 locally strengthens the hinge mounting area, distributing stress during door opening and closing and preventing cracking or deformation at the hinge mounting point. The support member 3, acting as an intermediate force transmission component, distributes the load from the hinge mounting point to the hinge mounting reinforcement plate 104, and then transfers it to the pillar reinforcement plate 103, the inner pillar plate 101, and the outer pillar plate 102, effectively preventing localized overload.

[0050] The support member 3 also restricts the relative displacement between the inner plate 101 and the outer plate 102 of the column, enhancing the overall torsional resistance of the column 1. The first connector 4 passes through the inner plate 101 and the column reinforcing plate 103, allowing force to be transmitted between the column 1 and the support member 3, effectively improving the deformation resistance of the column 1. The second connector 5 passes through the hinge mounting reinforcing plate 104 and the outer plate 102 of the column, allowing the dynamic load of the rear door hinge 2 to be transferred to the column 1 and the support member 3 through the second connector 5, effectively improving the structural strength and rigidity of the hinge mounting point.

[0051] like Figure 3 As shown, in some exemplary embodiments, the receiving cavity 10a includes a first receiving cavity 10a1 and a second receiving cavity 10a2, which are located on the front and rear sides of the column reinforcing plate 103, respectively.

[0052] Here, the receiving cavity 10a of the column 1 is further subdivided into a first receiving cavity 10a1 and a second receiving cavity 10a2. The first receiving cavity 10a1 and the second receiving cavity 10a2 are respectively arranged on the front and rear sides of the column reinforcing plate 103 and both extend along the vertical direction of the vehicle. This design can perform spatial partitioning and load isolation, significantly improving the structural performance of the column 1.

[0053] Specifically, the first receiving cavity 10a1 and the second receiving cavity 10a2 are arranged one after the other, so that the column 1 forms a structure of three-layer plate and two-layer cavity. The two-layer cavity effectively improves the bending stiffness, and the three-layer plate improves the stiffness in combination, which can significantly improve the bending capacity of the column 1 in the vertical direction, thereby improving the load capacity of the column 1.

[0054] Continue to refer to Figure 3 As shown, in one example, the pillar reinforcement plate 103 has a protruding portion 1031 that protrudes forward in the vehicle's front-rear direction. The protruding portion 1031 is attached to the pillar inner plate 101, and the first connector 4 is disposed through the protruding portion 1031.

[0055] Here, a protruding portion 1031 is provided on the column reinforcing plate 103, so that the column reinforcing plate 103 itself has good structural strength and rigidity. When applied to the column 1, it can further improve the structural strength and rigidity of the column 1, thereby improving the load-bearing capacity and deformation resistance of the column 1.

[0056] In the above implementation, the inner plate 101 of the column is spot-welded to the column reinforcing plate 103, and the protruding part 1031 is attached to the inner plate 101. The first connecting piece 4 is set through the protruding part 1031. This structure allows the support piece 3 to completely penetrate from the rear side wall of the column 1 to the front side wall of the column 1, so that the support frame has a good support capacity for the column 1 in the front and rear directions of the vehicle, and can effectively prevent the inner plate 101 of the column from deforming.

[0057] In one example, the hinge mounting reinforcement plate 104 is attached to the front side of the column outer plate 102, which can effectively improve the tensile and shear resistance of the hinge mounting point on the column outer plate 102, thereby effectively preventing the column outer plate 102 from deforming.

[0058] In one example, the hinge mounting reinforcement plate 104 is spot-welded to the column outer plate 102. The hinge mounting reinforcement plate 104 can effectively improve the rigidity of the column outer plate 102 and enhance its performance.

[0059] like Figures 1 to 4 As shown, in some exemplary embodiments, the tailgate hinge 2 includes an upper tailgate hinge 201 and a lower tailgate hinge 202, which are spaced apart in the vertical direction of the vehicle. The aforementioned support member 3 includes an upper support member 301 corresponding to the upper tailgate hinge 201 and a lower support member 302 corresponding to the lower tailgate hinge 202, which are spaced apart in the vertical direction of the vehicle.

[0060] In the above implementation, an upper hinge 201 and a lower hinge 202 are respectively provided for the tailgate, and corresponding upper support 301 and lower support 302 are provided. This allows the tailgate to have two connection areas with the vehicle body, resulting in better connection strength and forming two opposite force transmission paths, thereby improving the load-bearing capacity of the tailgate.

[0061] The upper support member 301 is arranged correspondingly to the upper hinge 201 of the tailgate, which can locally strengthen the mounting part of the upper hinge 201 and effectively distribute the concentrated load of the upper hinge 201. The lower support member 302 is arranged correspondingly to the lower hinge 202 of the tailgate, which can locally strengthen the mounting part of the lower hinge 202 and effectively distribute the concentrated load of the lower hinge 202.

[0062] The upper hinge 201 and lower hinge 202 of the tailgate are arranged at intervals in the vertical direction of the vehicle, and the upper support 301 and lower support 302 are arranged at intervals in the vertical direction of the vehicle, which can cover the full height range of the tailgate, effectively preventing stress concentration, thereby effectively preventing deformation caused by excessive load on the rear of the vehicle.

[0063] like Figure 3 As shown, in some exemplary embodiments, the front ends of the upper support 301 and the lower support 302 are each fitted with a first sleeve 30a, and the first connector 4 corresponds one-to-one with the first sleeve 30a. Each first connector 4 includes a bolt that is screwed to the corresponding first sleeve 30a.

[0064] It should be noted that the upper hinge 201 of the tailgate requires four bolts, and the upper support 301 has four first sleeves 30a embedded in it. The lower hinge 202 of the tailgate also requires four bolts, and the lower support 302 has four first sleeves 30a embedded in it. Each first sleeve 30a has threads, and each first sleeve 30a is screwed to the corresponding bolt through its own threads. The first sleeves 30a can be made of steel, for example, to improve the reliability of the installation of the upper hinge 201 and the lower hinge 202 of the tailgate.

[0065] In this embodiment, a first sleeve 30a is embedded in the upper support member 301 and the lower support member 302. The support member 3 can be made of a lightweight material, such as cast aluminum, while the first sleeve 30a can be made of a high-strength material, such as high-strength steel. The first sleeve 30a is responsible for connecting with the first fastener, which is beneficial for balancing the lightweight design of the vehicle body and the structural reinforcement effect on the pillar 1.

[0066] In another example, the rear ends of both the upper support 301 and the lower support 302 are fitted with second sleeves, which are not shown in the figure. The second connecting members 5 correspond one-to-one with the second sleeves, and each second connecting member 5 includes a bolt that is screwed to the corresponding second sleeve.

[0067] In this example, a second sleeve is embedded in the upper support 301 and the lower support 302. The second sleeve can be made of a high-strength material, such as high-strength steel, and is responsible for connecting with the second fastener. In conjunction with the support 3 made of a lighter material, it is beneficial to take into account both the lightweight design of the vehicle body and the structural reinforcement effect of the pillar 1.

[0068] like Figure 5 As shown, in some exemplary embodiments, the upper support 301 includes an upper support plate 3011 and a first upper support column 3012 integrally formed with the upper support plate 3011.

[0069] The first connecting member 4 and the second connecting member 5 connected to the upper support member 301 are respectively provided with the first upper support column 3012. Each first upper support column 3012 extends along the front and rear direction of the vehicle, and the two ends of each first upper support column 3012 are respectively connected to the corresponding first connecting member 4 and the second connecting member 5.

[0070] In one example, the front end of the first upper support column 3012 protrudes forward relative to the upper support plate 3011, and the rear end of the first upper support column 3012 protrudes rearward relative to the upper support plate 3011. There are two first upper support columns 3012. The front end of each first upper support column 3012 is connected to two first connectors 4, and the rear end of each first upper support column 3012 is connected to two second connectors 5. Each first upper support column 3012 extends through the entire receiving cavity 10a along the front-rear direction of the vehicle.

[0071] In the above implementation, the upper support plate 3011 and the first upper support column 3012 are integrally formed, so that when the upper support member 301 is subjected to load, the stress can be more evenly distributed on the entire structure, thereby significantly improving the overall structural strength of the upper support member 301.

[0072] The first upper support column 3012 extends along the longitudinal direction of the vehicle, and its two ends are connected to the corresponding first connector 4 and second connector 5, respectively. This structural layout enables the first upper support column 3012 to provide stable support force in the longitudinal direction of the vehicle, effectively dispersing and transferring loads from other components of the vehicle, and further enhancing the local strength and stability of the entire support structure.

[0073] Furthermore, since the upper support plate 3011 and the first upper support column 3012 are integrally formed, there is no need to perform separate connection operations on these two components during assembly, thereby reducing assembly steps and simplifying the assembly process. This not only saves assembly time but also reduces the risk of quality problems caused by improper assembly operations.

[0074] like Figure 6 As shown, in some exemplary embodiments, the lower support member 302 includes a lower support plate 3021, and a first lower support column 3022 and a second lower support column 3023 integrally formed with the lower support plate 3021; ​​when viewed in the front-rear direction of the vehicle, the first lower support column 3022 and the second lower support column 3023 are arranged in a staggered manner.

[0075] The first connecting member 4, which is connected to the lower support member 302, is correspondingly provided with the first lower support column 3022, and the first lower support column 3022 is connected to the corresponding first connecting member 4. The second connecting member 5, which is connected to the lower support member 302, is correspondingly provided with the second lower support column 3023, and the second lower support column 3023 is connected to the corresponding second connecting member 5.

[0076] In one example, the rear end of the first lower support column 3022 protrudes rearward relative to the lower support plate 3021. There are two first lower support columns 3022, and the front end of each first lower support column 3022 is connected to two first connectors 4.

[0077] The front end of the second lower support column 3023 protrudes forward relative to the lower support plate 3021, and the rear end of the second lower support column 3023 protrudes backward relative to the lower support plate 3021. There are two second lower support columns 3023, and the rear end of each second lower support column 3023 is connected to two second connectors 5.

[0078] In the above implementation, the first lower support column 3022, the second lower support column 3023 and the lower support plate 3021 are designed as an integral part, which makes the lower support member 302 have high structural strength. The staggered arrangement of the first lower support column 3022 and the second lower support column 3023 can make the arrangement position of the lower support member 302 more flexible and easy to adapt to the vehicle body structure. At the same time, it can also take into account the lightweight requirements of the lower support member 302 and the strengthening effect on the column 1.

[0079] Since the lower support plate 3021 is integrally formed with the first lower support column 3022 and the second lower support column 3023, there is no need to perform separate connection operations on these components during assembly, thereby reducing assembly steps and simplifying the assembly process. This not only saves assembly time but also reduces the risk of quality problems caused by improper assembly operations.

[0080] like Figure 4 and Figure 5 As shown, in some exemplary embodiments, at least one of the front and rear sides of the upper support member 301 is provided with a first reinforcing rib 3013 along the front-rear direction of the vehicle. This can effectively enhance the structural strength of the upper support member 301, and these first reinforcing ribs 3013 have a stress-dispersing effect, enabling the upper support member 301 to achieve a higher load-bearing capacity with less material, which is beneficial to the lightweight design of the vehicle body.

[0081] In one example, the upper support 301 also includes a second upper support column 3014 integrated with the upper support plate 3011. The rear end of the second upper support column 3014 protrudes rearward relative to the upper support plate 3011, and the front end of the second upper support column 3014 is connected to a third connector, such as a bolt, through the inner plate 101 of the column and the hinge mounting reinforcement plate 104.

[0082] The upper support member 301 is provided with a first reinforcing rib 3013 on both the front and rear sides. The first reinforcing rib 3013 on the front side includes two longitudinal reinforcing ribs extending in the direction of vehicle upward, a transverse reinforcing rib connecting the two longitudinal reinforcing ribs, and an oblique reinforcing rib connecting the second upper support column 3014 and one of its longitudinal reinforcing ribs. This can effectively improve the structural strength of the upper support member 301. Furthermore, reinforcing columns are provided on the transverse reinforcing ribs, longitudinal reinforcing ribs, and oblique reinforcing ribs to effectively improve the reinforcement effect.

[0083] like Figure 4 and Figure 6 As shown, along the front-rear direction of the vehicle, at least one of the front and rear sides of the lower support member 302 is provided with a second reinforcing rib 3024.

[0084] In one example, the lower support member 302 is provided with a second reinforcing rib 3024 on both the front and rear sides, and the second reinforcing rib 3024 on the front and rear sides each includes two longitudinal reinforcing ribs extending in the direction upward along the vehicle, and each longitudinal reinforcing rib is provided with a reinforcing post to further improve the reinforcing effect.

[0085] Here, a second reinforcing rib 3024 is provided on at least one side of the lower support member 302 in the front-rear direction, which can enhance the structural strength of the lower support member 302. These second reinforcing ribs 3024 have a stress-dispersing effect and enable the lower support member 302 to achieve a higher load-bearing capacity with less material, which is beneficial to the lightweight design of the vehicle body.

[0086] It should be noted that in some of the exemplary embodiments, both the upper support 301 and the lower support 302 are formed using a die-casting process. Using die-casting can significantly improve production efficiency. Die-casting molds have high precision and stability, ensuring the dimensional and shape accuracy of the upper support 301 and the lower support 302. Furthermore, the die-cast parts have small dimensional deviations and good interchangeability, which is beneficial for subsequent assembly work.

[0087] It is worth noting that, regarding the rear structure of the vehicle body in this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 3 As shown, it may include, for example, a pillar 1, a rear door hinge 2 mounted on the pillar 1, and a support member 3 disposed within the pillar 1.

[0088] The column 1 includes an inner column plate 101 and an outer column plate 102 that enclose a receiving cavity 10a, and a column reinforcing plate 103 and a hinge mounting reinforcing plate 104 disposed within the receiving cavity 10a. The support member 3 is located between the column reinforcing plate 103 and the hinge mounting reinforcing plate 104. The front end of the support member 3 is connected to a first connecting member 4 that passes through the inner column plate 101 and the column reinforcing plate 103, and the rear end of the support member 3 is connected to a second connecting member 5 that passes through the rear door hinge 2, the outer column plate 102, and the hinge mounting reinforcing plate 104.

[0089] In the preferred embodiment of the above-mentioned rear structure of the vehicle body, the specific setting and arrangement of the pillar 1, support member 3, etc. can still be referred to the description in the above-mentioned exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the pillar 1, support member 3, etc. can also be referred to the description in the above-mentioned exemplary embodiments.

[0090] An embodiment of the second aspect of this application provides a vehicle having the rear body structure described in the embodiment of the first aspect of this application.

[0091] The vehicle in this embodiment, by applying the rear body structure of the vehicle body in the first aspect of this application, can effectively improve the structural strength and rigidity of the hinge mounting point, as well as the strength and rigidity of the rear body structure. Under the condition of being subjected to a large force at the side-opening rear door hinge 2, the above-mentioned rear body structure can effectively prevent the pillar 1 from deforming, thereby improving the safety and reliability of the vehicle application.

[0092] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this application should be included within the protection scope of the claims of this application.
