The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] The following is for reference. Figures 1-5 A door ring structure 100 according to a first aspect embodiment of the present invention is described.

[0031] like Figures 1-5 As shown, the door ring structure 100 according to the first aspect embodiment of the present utility model includes: a plurality of connecting components.

[0032] Specifically, the plurality of connecting components are connected and enclose the door ring structure 100, and the thicknesses of at least two of the plurality of connecting components are different. It can be understood that the thicknesses of the plurality of connecting components are not all the same, and the thickness of at least one of the plurality of connecting components is different from the thickness of another connecting component. Thus, the side impact performance of the door ring structure 100 is improved while the weight and cost of the door ring structure 100 are considered.

[0033] According to the door ring structure 100 of the embodiment of the present application, the structural integrity of the door ring structure 100 is ensured by the plurality of connecting components with different thicknesses, the side impact safety of the door ring structure 100 is ensured, the side impact performance of the door ring structure 100 is improved, the weight and cost of the door ring structure 100 are reduced, and thus the stringent side impact regulation target is achieved under the weight target condition.

[0034] Further, the materials of at least two of the plurality of connecting components are different. It can be understood that the materials of the plurality of connecting components are not all the same, and the material of at least one of the plurality of connecting components is different from the material of another connecting component of the plurality of connecting components.

[0035] In short, the door ring structure 100 of the embodiment of the present application not only adopts the splicing mode with variable thickness, but also adopts the splicing mode with variable material, so that the stringent side impact regulation target is achieved under the weight target condition.

[0036] In some embodiments of the present application, as shown in Figure 1 and Figure 2 , the plurality of connecting components include: a first connecting piece 1, a second connecting piece 2, a third connecting piece 3, a fourth connecting piece 4, and a fifth connecting piece 5, the upper end of the first connecting piece 1 is connected with the front end of the second connecting piece 2, the lower end of the first connecting piece 1 is connected with the front end of the third connecting piece 3, the lower end of the second connecting piece 2 is connected with the upper end of the third connecting piece 3, the rear end of the third connecting piece 3 is connected with the lower end of the fifth connecting piece 5, the rear end of the second connecting piece 2 is connected with the upper end of the fourth connecting piece 4, and the lower end of the fourth connecting piece 4 is connected with the upper end of the fifth connecting piece 5. It can be understood that the second connecting piece 2 is arranged corresponding to the B pillar, and the fourth connecting piece 4 is arranged corresponding to the C pillar. In this way, a closed loop structure is formed, each connecting piece is connected with other connecting pieces, forming a stable geometric configuration, ensuring that the entire door ring has good integrity and stability.

[0037] Preferably, the first connecting piece 1, the second connecting piece 2, the third connecting piece 3, the fourth connecting piece 4, the fifth connecting piece 5, and the B pillar inner patch plate 6 are integrally formed, and before forming, a mother plate with different materials and different thicknesses is spliced and integrally formed after hot stamping, and as shown in Figure 5As shown, the B-pillar lower hinge plate 7 is welded to the B-pillar inner patch plate 6 and the third connecting piece 3.

[0038] In some embodiments of the present application, as shown in Figure 2 As shown, the door ring structure 100 further comprises a B-pillar inner patch plate 6 and a B-pillar lower hinge plate 7. The B-pillar inner patch plate 6 is arranged on the second connecting piece 2, and the B-pillar lower hinge plate 7 is arranged at the connection position of the second connecting piece 2 and the third connecting piece 3, and the upper end of the B-pillar lower hinge plate 7 is connected to the lower end of the B-pillar inner patch plate 6. It can be understood that the B-pillar inner patch plate 6 is arranged on the second connecting piece 2 to strengthen the B-pillar structure, and the upper end of the B-pillar lower hinge plate 7 is connected to the lower end of the B-pillar inner patch plate 6 to ensure the continuity and stability between the B-pillar lower hinge plate 7 and the B-pillar inner patch plate 6. Thus, for positions that need to bear greater stress, the B-pillar inner patch plate 6 and the B-pillar lower hinge plate 7 can increase the strength of the local area, prolong the service life of the entire door ring structure 100, reduce damage caused by long-term use, and thus ensure the side crash safety of the door ring structure 100 and improve the side crash performance of the door ring structure 100.

[0039] Further, as shown in Figure 3 and Figure 4 As shown, the third connecting piece 3 and the fifth connecting piece 5 are both formed with an inducing portion. It can be understood that when the B-pillar region is impacted, the inducing portion can ensure that the B-pillar deformation is concentrated at the bottom, and the sufficient deformation of the bottom causes a smaller probability of tearing the bottom region. After the collision energy is concentrated and absorbed by the bottom region of the B-pillar, the deformation speed of the dummy's chest region corresponding to the upper middle region of the B-pillar is reduced, thereby protecting the dummy.

[0040] Preferably, the inducing portion is formed as an inducing groove 8, and the depth of the inducing groove 8 is 10 mm.

[0041] In some embodiments of the present application, the thickness of the first connecting piece 1 is 1.6 mm, the thickness of the second connecting piece 2 is 1.4 mm, the thickness of the third connecting piece 3 is 1.8 mm, the thickness of the fourth connecting piece 4 is 1.0 mm, the thickness of the fifth connecting piece 5 is 1.0 mm, the thickness of the B-pillar inner patch plate 6 is 1.8 mm, and the thickness of the B-pillar lower hinge plate 7 is 1.6 mm. Furthermore, the first connecting piece 1 is a 1500hs hot-formed steel material piece, the second connecting piece 2 is a 1500hs hot-formed steel material piece, the third connecting piece 3 is a 600hs hot-formed steel material piece, the fourth connecting piece 4 is a 1500hs hot-formed steel material piece, the fifth connecting piece 5 is a 600hs hot-formed steel material piece, the B-pillar inner patch plate 6 is a 1500hs hot-formed steel material piece, and the B-pillar lower hinge plate 7 is a 340 / 590DP steel material piece.

[0042] It can be understood that in the side impact condition, the whole vehicle is subjected to a huge impact force from the barrier, the connection of the front and rear doors and the vehicle body structure is only at two hinge positions and the door lock position, and most of the impact energy is transmitted to the body-in-white. In the side impact condition, the main force receiving component is the B-pillar region, and then according to the whole vehicle with different wheelbase, it can be transmitted to the C-pillar or A-pillar.

[0043] When the B-pillar region is impacted, due to the B-pillar bottom being provided with a soft zone material and the induced groove 8, the high strength of the middle and upper parts of the B-pillar compared with the bottom can ensure that the deformation of the B-pillar is concentrated at the bottom, and the ductility of the 600hs hot forming steel is more than 3 times the ductility of the 1500hs hot forming steel, so that the bottom can be fully deformed. The full deformation of the bottom causes a small probability of tearing of the bottom region. After the collision energy is concentrated and absorbed by the bottom region of the B-pillar, the deformation speed of the chest region of the dummy corresponding to the middle and upper regions of the B-pillar is reduced, thereby protecting the dummy. With the increase of the weight of the whole vehicle, even if the fracture elongation rate of the 600hs hot forming steel, a slight tearing of the bottom of the B-pillar can still occur. Through the connection of the B-pillar lower hinge plate 7 and the third connecting piece 3, the tearing risk of the bottom of the B-pillar is further reduced, and the integrity of the B-pillar structure is ensured.

[0044] At the same time, the rear C-pillar position is also impacted by the barrier. Since the impact on the C-pillar is smaller than that on the B-pillar, the strength of the C-pillar region is designed to be weaker than that of the B-pillar region. The door ring structure 100 of the utility model embodiment is adopted, and the deformation of the C-pillar is also concentrated at the bottom, the deformation of the chest and abdominal region of the dummy corresponding to the middle and upper parts of the C-pillar is reduced, and the deformation speed of the rear door is reduced, thereby protecting the dummy.

[0045] In summary, the door ring structure 100 of the utility model embodiment not only adopts a variable-thickness splicing method, but also adopts a variable-material splicing method, so as to achieve strict side impact regulation targets under the condition of weight targets. Specifically, while the strength of the B-pillar lower hinge plate 7 is ensured, a hot forming material with lower strength and higher ductility, 600hs hot forming steel (the fracture elongation rate of 1500hs hot forming steel is 6%, and the fracture elongation rate of 600hs hot forming steel is more than 20%), is adopted at the bottom of the B-pillar. In order to ensure the stability of the deformation, the induced groove 8 is increased, the hinge plate and the B-pillar are connected, and the thickness of the B-pillar bottom sample is increased, so as to realize a deformation mode in which the overall deformation of the B-pillar region is stably concentrated at the bottom, and ensure that the bottom of the B-pillar is not torn. At the same time, the deformation is controlled within a degree of accurately protecting the dummy injury. The C-pillar region adopts a 1.0mm plate for the purpose of weight, and the different material splicing method ensures the deformation of the bottom of the C-pillar, thereby reducing the deformation amount of the upper part of the C-pillar and ensuring the score of the rear dummy.
