Description

Technical Field

[0001] This invention relates to the field of vehicle technology, specifically to an anchor ring mounting structure, a rear body structure, a body-in-white, a body, and a vehicle. Background Technology

[0002] As automotive safety regulations continue to improve, some countries and regions have raised the bar for the anchoring capabilities of vehicles in transport securing, towing, or restraint systems. This is especially true in the logistics of transporting complete vehicles, where reliable anchor points are required on the vehicle body to securely restrain luggage or cargo using straps or other fastening devices.

[0003] In existing vehicle body structures, the rear area typically lacks specific reinforcement design for anchor ring loads. For example, the local structural strength of areas such as the reinforcing plate on the rear wheel arch inner panel and the rear bulkhead connecting plate is insufficient to meet the demands of high-intensity tensile conditions. In practical applications, directly placing anchor ring mounting points on the reinforcing plate on the rear wheel arch inner panel and the rear bulkhead connecting plate can easily lead to localized deformation, tearing, or even structural failure under high-intensity tensile conditions, affecting overall vehicle safety and regulatory compliance. Summary of the Invention

Figure 6 for Figure 2 The diagram shows the connection relationship between the reinforcing member and the first anchor ring. Figure 7 for Figure 1 A schematic diagram showing the connection relationship between the rear connecting plate and the rear inner plate of the anchor ring installation structure. Figure 8 for Figure 7 The diagram shows the connection relationship between the rear connecting plate and the second reinforcing plate. Figure 9 for Figure 8 A color rendering of the connection relationship between the rear connecting plate and the second reinforcing plate shown. Figure 10 for Figure 8 The diagram shows the structure of the second reinforcing plate. Figure 11 for Figure 8 The diagram shows the connection relationship between the rear connecting plate and the second anchor ring. Figure 12 for Figure 11 The diagram shows the structure of the second anchor ring.

[0031] like Figures 1-12 As shown, the anchor ring installation structure includes a reinforcing member 1, a first reinforcing plate 2, a first anchor ring 3, a rear connecting plate 4, a second reinforcing plate 5, and a second anchor ring 6.

[0032] The reinforcing member 1 is used to connect with the inner rear wheel arch panel 7; the first reinforcing plate 2 is connected to the reinforcing member 1 on the side facing outwards; the first anchor ring 3 is connected to the reinforcing member 1 on the side facing inwards, and is connected to the first reinforcing plate 2 by means of fastener 23; one end of the rear bulkhead connecting plate 4 is used to connect with the inner rear bulkhead panel 8, and the other end of the rear bulkhead connecting plate 4 is connected to the inner rear wheel arch panel 7 through the CD pillar connecting plate 9; the second reinforcing plate 5 is connected to the rear bulkhead connecting plate 4 on the side facing outwards; the second anchor ring 6 is connected to the rear bulkhead connecting plate 4 on the side facing inwards, and is connected to the second reinforcing plate 5 by means of fastener 23.

[0033] The reinforcing member 1 is a reinforcing plate on the inner plate of the rear wheel arch. The left and right sides of the reinforcing member 1 extending in the direction of extension are respectively used for welding to the inner plate of the rear wheel arch 7. The middle part of the reinforcing member 1 protrudes, so that after connecting with the inner plate of the rear wheel arch 7, a cavity can be formed between the two to enhance local strength. During assembly, the first reinforcing plate 2 is fixedly connected to the middle protruding part of the reinforcing member 1 facing outwards. The first anchor ring 3 is arranged on the side of the reinforcing member 1 facing inwards, corresponding to the position of the first reinforcing plate 2, and fasteners 23 are used to sequentially pass through the first anchor ring 3, the reinforcing member 1, and the first reinforcing plate 2 to achieve a fixed connection between the three components. The reinforcing member 1 of the first reinforcing plate 2 and the first anchor ring 3 is welded to the inner plate 7 of the rear wheel arch. In addition, the second reinforcing plate 5 is fixedly connected to the side of the rear connecting plate 4 facing outwards. The second anchor ring 6 is arranged on the side of the rear connecting plate 4 facing inwards, corresponding to the position of the second reinforcing plate 5. Fasteners 23 pass through the second anchor ring 6, the rear connecting plate 4 and the second reinforcing plate 5 in sequence to achieve a fixed connection between the second anchor ring 6, the rear connecting plate 4 and the second reinforcing plate 5. The rear connecting plate 4, which is fixed with the second reinforcing plate 5 and the second anchor ring 6, is connected to the inner plate 8 of the rear arch and connected to the inner plate 7 of the rear wheel arch via the CD pillar connecting plate 9.

[0034] When the first anchor ring 3 and the second anchor ring 6 securely restrain luggage or cargo using straps or other fixing devices, and are subjected to the pulling force of the straps or towing device, the tensile load on the first anchor ring 3 is transferred to the first reinforcing plate 2. The first reinforcing plate 2 then distributes the tensile force to the reinforcing member 1, namely the reinforcing plate on the inner rear wheel arch, the inner rear wheel arch 7, and the connecting plate 20 connecting the reinforcing member 1 to the rear floor crossbeam 21. This force is further transferred to the left / right longitudinal beams at the rear of the vehicle, the rear floor crossbeam, the rear floor 22, and other main load-bearing structures. Similarly, the tensile load on the second anchor ring 6 is transferred to the second reinforcing plate 5. The second reinforcing plate 5 then distributes the tensile force to the rear bulkhead connecting plate 4, the D-pillar connecting plate 19, and the CD-pillar connecting plate 9. This force is further transferred to the D-pillar body and the rear bulkhead crossbeam, and other main load-bearing structures. This multi-path load distribution structure avoids load concentration in a single local area, significantly reducing the risk of local structural failure and fracture.

[0035] The anchor ring installation structure of this invention, by adding a first reinforcing plate 2 to the reinforcing member 1 (i.e., the reinforcing plate on the inner plate of the rear wheel arch) on the side facing outwards, and arranging the first anchor ring 3 on the side facing inwards corresponding to the first reinforcing plate 2, and fixing the three together, and by adding a second reinforcing plate 5 to the side facing outwards of the rear connecting plate 4, and arranging the second anchor ring 6 on the side facing inwards corresponding to the second reinforcing plate 5, and fixing the three together, can effectively improve the load-bearing capacity of the installation area of ​​the first anchor ring 3 and the second anchor ring 6, improve local strength and stiffness, optimize the load transfer path, disperse the load to a larger area, reduce local stress concentration, construct multi-path load transfer, improve structural redundancy, reduce the risk of structural deformation and structural failure during transportation and use, improve the safety of the whole vehicle, and fully meet the relevant regulations for anchor point strength and safety.

[0036] like Figure 1 As shown, in this embodiment, the reinforcing member 1, i.e., the reinforcing plate on the inner panel of the rear wheel arch, is fixedly connected to the side of the inner panel of the rear wheel arch 7 facing the vehicle interior. The rear connecting plate 4 is fixedly connected to the inner panel of the rear wheel arch 8. Furthermore, within the vehicle structure, two reinforcing members 1 and two rear connecting plates 4 are respectively provided, symmetrically arranged left and right along the width direction of the vehicle body. Taking one side as an example... Figure 2As shown, the reinforcing member 1 is welded to the inner rear wheel arch panel 7 facing the vehicle interior. Specifically, the reinforcing member 1 extends vertically, with flanges on both sides and a central protrusion facing the vehicle interior. The reinforcing member 1 is welded to the inner rear wheel arch panel 7 via the flanges on both sides, and a cavity is formed between the central protrusion and the inner rear wheel arch panel 7. The lower end of the reinforcing member 1 is connected to the connecting plate 20, and there are two connecting plates 20. The two connecting plates 20 are set at a certain angle, so that the first end of one connecting plate 20 is fixedly connected to the lower end of the reinforcing member 1, the second end is fixedly connected to the first end of the other connecting plate 20, and the second end of the other connecting plate 20 is fixedly connected to the crossbeam 21 on the rear floor. Figure 3 As shown, the side of the reinforcing member 1 facing the line of sight is the side facing outwards from the vehicle. The first reinforcing plate 2 is fixedly connected to the side of the reinforcing member 1 facing outwards from the vehicle at a position slightly below the center in the height direction, so that it will not be exposed inside the vehicle, thereby improving aesthetics. Correspondingly, as... Figure 2 and Figure 6 As shown, the side of the reinforcing member 1 facing the line of sight is the side facing the interior of the vehicle. The first anchor ring 3 is fixedly connected to the reinforcing member 1 at a position slightly below the center of its height in the direction of the side facing the interior of the vehicle. The first anchor ring 3 is positioned correspondingly to the first reinforcing plate 2. The fastener 23 passes through the first anchor ring 3, the reinforcing member 1, and the first reinforcing plate 2 in sequence, thereby achieving a fixed connection between the first anchor ring 3, the reinforcing member 1, and the first reinforcing plate 2. To clearly illustrate the relative positional relationship between the first reinforcing plate 2 and the reinforcing member 1, as shown... Figure 4 The image shown is a color-rendered perspective view of the reinforcing member 1 and the first reinforcing plate 2. The first reinforcing plate 2 is fixedly connected to the reinforcing member 1 at a position slightly below the center of the reinforcing member 1 in the height direction.

[0037] like Figure 7 As shown, in this embodiment, the upper end of the rear connecting plate 4 is fixedly connected to the D-pillar connecting plate 19, the lower front end is fixedly connected to the rear inner plate 8, and the lower end is fixedly connected to the CD-pillar connecting plate 9. The CD-pillar connecting plate 9 is further fixedly connected to the rear wheel arch inner plate 7. Figure 8 and Figure 9 As shown, on the side of the rear connecting plate 4 facing outwards, near the upper end of the height, the second reinforcing plate 5 is fixedly connected to the rear connecting plate 4 and will not be exposed inside the vehicle, thus improving aesthetics. Correspondingly, as... Figure 7 and Figure 11As shown, on the side of the rear connecting plate 4 facing the inside of the vehicle, near the upper end of the height, at the position corresponding to the second reinforcing plate 5, the second anchor ring 6 is arranged. The fastener 23 passes through the second anchor ring 6, the rear connecting plate 4 and the second reinforcing plate 5 in sequence to realize the fixed connection between the second anchor ring 6, the rear connecting plate 4 and the second reinforcing plate 5.

[0038] In this embodiment, the first reinforcing plate 2 is fitted to the reinforcing member 1 and fixedly connected by welding. The second reinforcing plate 5 is fitted to the rear connecting plate 4 and fixedly connected by welding, for example, by spot welding or laser welding. To improve the uniformity of load transfer, the weld points are evenly distributed along the contours of the first reinforcing plate 2 and the second reinforcing plate 5. This fitted welding connection method can significantly improve the bending stiffness of this area and prevent local bending deformation of the plates when the anchor ring is under tension.

[0039] Furthermore, the external dimensions of the first reinforcing plate 2 and the second reinforcing plate 5 can be set to fit perfectly with the surface of the original installation area, so that they can be directly integrated into the existing body welding production process without the need to develop new molds or adjust the production line layout. Vehicle manufacturers can directly use the original process for production without increasing production preparation costs excessively.

[0040] The first anchor ring 3 and the second anchor ring 6 each include an anchor ring body and a base, and both can be existing mature anchor rings. Their specific structural composition will not be described in detail here.

[0041] Depending on the actual application, the first reinforcing plate 2 and the second reinforcing plate 5 can be of any shape and size, as long as they can be fixedly connected to the reinforcing member 1 and the rear connecting plate 4. Furthermore, the first anchor ring 3 and the second anchor ring 6 are arranged at corresponding positions on the reinforcing member 1 and the rear connecting plate 4. With the help of fasteners 23, the first anchor ring 3, the reinforcing member 1 and the first reinforcing plate 2 can be fixedly connected, as can the second anchor ring 6, the rear connecting plate 4 and the second reinforcing plate 5. This can improve the load-bearing capacity of the installation area of ​​the first anchor ring 3 and the second anchor ring 6, increase the local strength and stiffness, and allow the load to be distributed to a larger area, reducing local stress concentration. This can reduce the risk of structural deformation and structural failure during transportation and use, thereby better meeting the usage requirements under vehicle transportation, fixing, and towing conditions. The specific arrangement positions of the first reinforcing plate 2 and the first anchor ring 3 on the reinforcing member 1, and the specific arrangement positions of the second reinforcing plate 5 and the second anchor ring 6 on the rear connecting plate 4, can be adjusted according to the actual situation. Preferably, the installation positions of the first reinforcing plate 2 on the reinforcing member 1 and the second reinforcing plate 5 on the rear connecting plate 4 correspond to the anchor ring installation areas already reserved on the original vehicle body, so that there is no need to adjust the overall layout of the rear of the vehicle body, and the effective storage space of the luggage compartment will not be occupied, and the daily use performance of the vehicle will not be affected.

[0042] Optionally, the first reinforcing plate 2 is provided with a first flange 10. This configuration, by adding the first flange 10, can improve the local bending stiffness of the first reinforcing plate 2, and at the same time increase the contact area between the first reinforcing plate 2 and the reinforcing member 1, which is beneficial to improving the connection stability between the two.

[0043] like Figures 3-5 As shown, in this embodiment, the upper and left edges of the first reinforcing plate 2 are respectively provided with the first flange 10, which extends a certain distance. The two first flanges 10 are respectively set at a certain angle to the first reinforcing plate 2. Specifically, the first flange 10 on the left edge is set approximately perpendicular to the first reinforcing plate 2, and the first flange 10 on the upper edge is set at an obtuse angle to the first reinforcing plate 2, so as to conform to the surface extension trend of the reinforcing member 1, thereby facilitating the connection between the first reinforcing plate 2 and the reinforcing member 1.

[0044] In addition, the first flange 10 can also be partially spot welded to the adjacent rear wheel arch inner plate 7, which is equivalent to fixing the first reinforcing plate 2 to the two adjacent surfaces of the reinforcing member 1 and the rear wheel arch inner plate 7 at the same time, thereby further improving the structural integrity of the entire installation area and preventing the first reinforcing plate 2 from warping and deforming under stress alone.

[0045] Depending on the actual application, the specific position of the first flange 10 on the edge of the first reinforcing plate 2 can be adjusted. The included angle between the first flange 10 and the first reinforcing plate 2, the extension length of the first flange 10, and the number of first flanges 10 can all be adjusted according to the shape change of the reinforcing member 1.

[0046] Optionally, the second reinforcing plate 5 is provided with a second flange 11. This configuration, by adding the second flange 11, can improve the local bending stiffness of the second reinforcing plate 5, and at the same time increase the contact area between the second reinforcing plate 5 and the rear connecting plate 4, which is beneficial to improving the connection stability between the two.

[0047] like Figures 8-10 As shown, in this embodiment, the second reinforcing plate 5 has a second flange 11 on its left side edge, which extends a certain distance. The second flange 11 is set at a certain angle with the rear connecting plate 4 to fit the surface extension trend of the rear connecting plate 4, thereby facilitating the connection between the second reinforcing plate 5 and the rear connecting plate 4.

[0048] Depending on the actual application, the specific position of the second flange 11 on the edge of the second reinforcing plate 5 can be adjusted. The included angle between the second flange 11 and the second reinforcing plate 5, the extension length of the second flange 11, and the number of second flanges 11 can all be adjusted according to the shape of the rear connecting plate 4.

[0049] Optionally, the first reinforcing plate 2 is provided with a first reinforcing rib 12. Providing a reinforcing rib structure can further enhance the structural strength of the first reinforcing plate 2 and prevent it from deforming under external forces.

[0050] like Figure 3 and Figure 5 As shown, in this embodiment, the first reinforcing rib 12 is provided at approximately the middle position of the first reinforcing plate 2, and bends downward until it extends to the lower edge end, presenting an overall "n" shape.

[0051] Depending on the actual application, the position of the first reinforcing rib 12 on the first reinforcing plate 2 can be adjusted, as can the number of the first reinforcing ribs 12 and the specific extension shape of the first reinforcing rib 12.

[0052] Optionally, the second reinforcing plate 5 is provided with a second reinforcing rib 13. The addition of the reinforcing rib structure can further enhance the structural strength of the second reinforcing plate 5 and prevent it from deforming under external forces.

[0053] like Figures 8-10 As shown, in this embodiment, the second reinforcing rib 13 is provided at approximately the middle and upper positions of the second reinforcing plate 5, and the second reinforcing rib 13 extends horizontally for a certain distance before bending upwards until it extends to the upper edge of the second reinforcing plate 5, forming an overall "L" shape.

[0054] Figure 10 To conceal the rear connecting plate 4, the connection relationship between the second reinforcing plate 5 and the second anchor ring 6 is shown, as follows: Figures 8-10 As shown, the fastener 23 passes through the second anchor ring 6, the rear connecting plate 4 and the second reinforcing plate 5 in sequence within the enclosure of the L-shaped second reinforcing rib 13, thereby connecting the three. The second reinforcing rib 13 can quickly disperse the tensile force borne by the through hole of the fastener 23 through the second reinforcing plate 5 to the surrounding area, effectively reducing the stress peak around the through hole and preventing plastic deformation or edge tearing of the through hole under large tensile force.

[0055] Depending on the actual application, the position of the second reinforcing rib 13 on the second reinforcing plate 5 can be adjusted, as can the number of the second reinforcing ribs 13 and the specific extension shape of the second reinforcing rib 13.

[0056] Optionally, the first reinforcing plate 2 and the reinforcing member 1 are respectively provided with a first recessed platform (not shown). This arrangement is equivalent to locally thickening the first reinforcing plate 2 and the reinforcing member 1 at the first recessed platform position, which can further improve the local structural strength.

[0057] Optionally, the first reinforcing plate 2, the reinforcing member 1, and the first anchor ring 3 are bolted together, with the bolts penetrating the first recessed platform. Using bolts to achieve a fixed connection between the first reinforcing plate 2, the reinforcing member 1, and the first anchor ring 3 simplifies the connection method, facilitates assembly and operation, and because the bolts penetrate the first recessed platform, the nuts that mate with the bolts, after being threaded into the bolts within the recessed area of ​​the first recessed platform, will not protrude beyond the surface height of the first reinforcing plate 2, thus not occupying additional space.

[0058] Optionally, the second reinforcing plate 5 and the rear connecting plate 4 are respectively provided with a second recessed platform 14. This arrangement is equivalent to locally thickening the second reinforcing plate 5 and the rear connecting plate 4 at the location of the second recessed platform 14, which can further improve the local structural strength.

[0059] like Figures 8-10 As shown, in this embodiment, a second recessed platform 14 is provided in the upper region of the second reinforcing plate 5, and a second reinforcing rib 13 is provided at the edge of the second recessed platform 14. Correspondingly, the rear connecting plate 4 is also provided with a second recessed platform 14 in the corresponding region, thereby ensuring that the second reinforcing plate 5 and the rear connecting plate 4 can be welded together.

[0060] Optionally, the second reinforcing plate 5, the rear connecting plate 4, and the second anchor ring 6 are bolted together, with the bolts penetrating the second recessed platform 14. Using bolts to achieve a fixed connection between the second reinforcing plate 5, the rear connecting plate 4, and the second anchor ring 6 simplifies the connection method, facilitates assembly and operation, and because the bolts penetrate the second recessed platform 14, the nuts installed with the bolts are threaded into the recessed area of ​​the second recessed platform 14 and do not protrude beyond the surface height of the second reinforcing plate 5, thus not occupying additional space.

[0061] like Figures 8-10 As shown, in this embodiment, the bolt passes through the second anchor ring 6, the rear connecting plate 4, and the second reinforcing plate 5 sequentially within the range of the second recessed platform 14, and is exposed in the second recessed platform 14. However, the exposed height is lower than the depth of the second recessed platform 14, that is, the exposed height of the bolt is lower than the surface height of the second reinforcing plate 5. Then, the nut is threaded to the bolt to achieve a stable connection between the second anchor ring 6, the rear connecting plate 4, and the second reinforcing plate 5. Moreover, after the nut is threaded to the bolt, the height of the nut does not exceed the depth of the second recessed platform 14 and is lower than the surface height of the second reinforcing plate 5.

[0062] To improve assembly efficiency, mounting holes can be pre-drilled on the second reinforcing plate 5 and the rear connecting plate 4, and the diameter of the mounting holes can match the mounting holes on the second anchor ring 6. Thus, when connecting the second anchor ring 6, the rear connecting plate 4 and the second reinforcing plate 5 with bolts, the bolts can pass directly through the second anchor ring 6, the rear connecting plate 4 and the second reinforcing plate 5 without the need for temporary hole drilling.

[0063] Optionally, the first reinforcing plate 2 is made of cold-rolled steel plate with a yield strength greater than or equal to 380 MPa.

[0064] Using cold-rolled steel plates with a yield strength ≥380MPa, the first reinforcing plate 2 possesses higher resistance to plastic deformation. Under load, it is less prone to permanent indentation and bending deformation, effectively dispersing and transferring localized concentrated stress. It provides support and protection for the connected reinforcing member 1, inhibiting crack initiation and propagation, and improving the overall structure's fatigue resistance and reliability. Furthermore, while meeting the same structural stiffness and safety performance requirements, this material allows for a suitable reduction in plate thickness, achieving lightweight components while ensuring structural strength. This contributes to overall weight reduction, while also reducing raw material consumption and controlling manufacturing costs.

[0065] In this embodiment, the first reinforcing plate 2 is stamped and formed. The cold-rolled steel plate has a uniform material structure, high flatness, and good dimensional accuracy. It has excellent stamping and forming process performance, which facilitates bending, punching, and forming. The springback of the part after forming is small, which can ensure the fitting accuracy between the first reinforcing plate 2 and the adjacent reinforcing member 1 and reduce the risk of assembly interference.

[0066] Optionally, the second reinforcing plate 5 is made of cold-rolled steel sheet with a yield strength greater than or equal to 380 MPa.

[0067] Using cold-rolled steel plates with a yield strength ≥380MPa, the second reinforcing plate 5 possesses higher resistance to plastic deformation. Under load, it is less prone to permanent indentation and bending deformation, effectively dispersing and transferring localized concentrated stress. It provides support and protection for the connected rear connecting plate 4, inhibiting crack initiation and propagation, and improving the overall structure's fatigue resistance and reliability. Furthermore, while meeting the same structural stiffness and safety performance requirements, this material allows for a suitable reduction in plate thickness, achieving lightweight components while ensuring structural strength. This contributes to overall weight reduction, while also reducing raw material consumption and controlling manufacturing costs.

[0068] In this embodiment, the second reinforcing plate 5 is stamped and formed. The cold-rolled steel plate has a uniform material structure, high flatness, and good dimensional accuracy. It has excellent stamping and forming process performance, which facilitates bending, punching, and forming. The springback of the part after forming is small, which can ensure the fitting accuracy between the second reinforcing plate 5 and the adjacent rear connecting plate 4 and reduce the risk of assembly interference.

[0069] Optionally, the thickness of the first reinforcing plate 2 is greater than the thickness of the reinforcing member 1.

[0070] The thicker first reinforcing plate 2 has a higher section modulus of bending, which can effectively reinforce and support the reinforcing member 1, significantly improving the overall bending stiffness of the reinforcing member 1, reducing the risk of bending and denting deformation under load, and preventing permanent plastic deformation such as bending and warping due to excessive force. Under load, the first reinforcing plate 2 can bear part of the concentrated stress, effectively dispersing the local stress level of the reinforcing member 1, reducing the stress amplitude of the reinforcing member 1, alleviating stress concentration, reducing the probability of cracking and fatigue failure of the reinforcing member 1, and improving the overall load-bearing performance.

[0071] In addition, the present invention only adds a thicker first reinforcing plate 2 locally, without thickening the reinforcing member 1 as a whole, which can reduce the overall material usage, control the weight and manufacturing cost of the whole machine, and balance structural strength and lightweight. The reinforcing member 1 maintains a relatively thin thickness, retaining its own molding, welding or assembly processability, while the thickened first reinforcing plate 2 achieves strength reinforcement.

[0072] Optionally, the thickness of the second reinforcing plate 5 is greater than the thickness of the rear connecting plate 4.

[0073] The thicker second reinforcing plate 5 has a higher section modulus of bending, which can effectively reinforce and support the rear connecting plate 4, significantly improving the overall bending stiffness of the rear connecting plate 4, reducing the risk of deflection and denting deformation under load, and preventing permanent plastic deformation such as bending and warping due to excessive stress. Under load, the second reinforcing plate 5 can bear part of the concentrated stress, effectively dispersing the local stress level of the rear connecting plate 4, reducing the stress amplitude of the rear connecting plate 4, alleviating stress concentration, reducing the probability of cracking and fatigue failure of the rear connecting plate 4, and improving the overall load-bearing performance.

[0074] In addition, the present invention only adds a thicker second reinforcing plate 5 locally, without thickening the rear connecting plate 4 as a whole, which can reduce the overall material usage, control the weight and manufacturing cost of the whole machine, and balance structural strength and lightweight. The rear connecting plate 4 maintains a relatively thin thickness, retaining its own forming, welding or assembly processability, while the thickened second reinforcing plate 5 achieves strength reinforcement.

[0075] Optionally, the first reinforcing plate 2 and the reinforcing member 1 are respectively provided with first positioning holes 15; the first anchor ring 3 is provided with a first positioning member 16, which is inserted into the first positioning hole 15. With this arrangement, the first anchor ring 3, the reinforcing member 1, and the first reinforcing plate 2 can be pre-positioned by the mutual insertion and cooperation of the first positioning member 16 and the first positioning hole 15, reducing the difficulty of assembly alignment, facilitating the installation of fasteners 23, and improving the efficiency of assembly operations.

[0076] like Figure 5 As shown, to clearly illustrate the cooperation relationship between the first anchor ring 3 and the first reinforcing plate 2, the reinforcing member 1 between them is hidden. The first positioning hole 15 is provided through the upper left side of the first reinforcing plate 2. Correspondingly, the reinforcing member 1 also has a first positioning hole 15 at the corresponding position. The first positioning member 16 on the first anchor ring 3 passes through the two corresponding first positioning holes 15 to achieve the pre-positioning of the relative positions of the first reinforcing plate 2, the reinforcing member 1 and the first anchor ring 3. Then, the bolts are passed through the first anchor ring 3, the reinforcing member 1 and the first reinforcing plate 2 in sequence to achieve the fixed connection between the three.

[0077] Optionally, the second reinforcing plate 5 and the rear connecting plate 4 are respectively provided with second positioning holes 17; the second anchor ring 6 is provided with a second positioning element 18, which is inserted into the second positioning hole 17. This arrangement, through the mutual insertion and cooperation of the second positioning element 18 and the second positioning hole 17, enables the pre-positioning of the second anchor ring 6, the rear connecting plate 4, and the second reinforcing plate 5, reducing the difficulty of assembly alignment, facilitating the installation of fasteners 23, and improving assembly efficiency.

[0078] like Figure 10 As shown, to clearly illustrate the cooperation relationship between the second anchor ring 6 and the second reinforcing plate 5, the rear connecting plate 4 between them is hidden. The second positioning hole 17 is provided through the upper right side of the second reinforcing plate 5. Correspondingly, the rear connecting plate 4 also has a second positioning hole 17 at the corresponding position. The second positioning member 18 on the second anchor ring 6 passes through the two corresponding second positioning holes 17 to achieve the pre-positioning of the relative positions of the second reinforcing plate 5, the rear connecting plate 4 and the second anchor ring 6. Then, the bolts are passed through the second anchor ring 6, the rear connecting plate 4 and the second reinforcing plate 5 in sequence to achieve the fixed connection between the three.

[0079] Verified through finite element simulation and real vehicle tensile testing, the anchor ring installation structure of this invention, under the test conditions required by regulations, did not exhibit any visible plastic deformation, tearing, or other structural failures at the two anchor ring installation positions. The maximum stress was far below the yield strength of the steel plate, meeting all relevant regulatory requirements. Furthermore, the total weight of the first reinforcing plate 2 and the second reinforcing plate 5 added in this solution is low, with negligible impact on the vehicle's curb weight. Moreover, the first reinforcing plate 2 and the second reinforcing plate 5 can be fully adapted to the original vehicle body shape, without requiring excessive adjustments to the overall layout of the rear of the vehicle, nor occupying effective storage space in the luggage compartment. No modifications to the original production molds or adjustments to the production line layout are needed; only two welding stations for reinforcing plates need to be added to the existing welding process for mass production. The increase in production costs is minimal, making it suitable for the modification and adaptation of existing models as well as the development and application of new models. This can help vehicle manufacturers quickly meet the regulatory requirements of different markets and enhance the market competitiveness of their products.
