Abstract
Description
Technical Field
[0001] The present application relates to the technical field of vehicles, and in particular, to an integrated door ring and a vehicle. Background Art
[0002] In recent years, new energy electric vehicles have rapidly emerged in the market. However, the application of their unique power structure - the battery pack - has significantly increased the weight of the whole vehicle, which is more than one-third heavier than that of traditional fuel vehicles. This change directly leads to a substantial increase in the impact force faced by the vehicle during a collision, posing more stringent requirements for the structural safety of the vehicle. In particular, the side wall structure in the front door opening area, as the first line of defense to protect the integrity of the cockpit and the safety of the driver, its design optimization is particularly important.
[0003] In the prior art, the reinforcement plate assembly around the front door opening of the white body mostly adopts a split structure, usually welded by four independent parts: the A-pillar reinforcement plate assembly, the upper side member reinforcement plate assembly, the B-pillar reinforcement plate assembly, and the sill reinforcement plate assembly. This split structure not only brings additional weight due to the double-layer plate lap joint, but also reduces the overall structural stiffness and consistency due to numerous welding points between the assemblies. In addition, to meet the collision safety standard, additional reinforcement plates need to be added, further increasing the weight of the vehicle body. Another attempt is the integrated door ring structure, which uses laser welding technology to weld the sheet materials of the A-pillar reinforcement plate, the upper side member reinforcement plate, the B-pillar reinforcement plate, and the sill reinforcement plate into one body and then stamping it again. Although it can reduce the double-layer plate lap joint area, the reinforcement plate still exists. Whether the reinforcement plate is separately molded and then spot-welded, or pre-spot-welded and then integrally stamped, it cannot fundamentally solve the problem of weight increase caused by the reinforcement parts, resulting in poor weight reduction effect and increased cost. Summary of the Utility Model
[0004] The present application aims to at least solve one of the technical problems existing in the prior art. For this reason, an object of the present application is to propose an integrated door ring. By combining and defining the integrated door ring with the first plate, the second plate, the third plate, and the fourth plate of different thicknesses, different regional thickness differences of the integrated door ring can be realized, so as to strengthen the areas with large forces in a targeted manner, while reducing the unnecessary material use in the areas with small forces, thereby achieving the effects of both reducing weight and increasing strength, canceling the additional reinforcement plates, and effectively reducing costs and weights.
[0005] The present application also proposes a vehicle having the above integrated door ring.
[0006] An integrated door ring according to an embodiment of the first aspect of the present application, the integrated door ring includes: an A-pillar assembly, an upper side member assembly, a B-pillar assembly, and a sill assembly are connected in sequence to define the integrated door ring; wherein the A-pillar assembly, the upper side member assembly, the B-pillar assembly, and the sill assembly are each formed by at least two of a first plate, a second plate, a third plate, and a fourth plate, and the first plate, the second plate, the third plate, and the fourth plate have different thicknesses.
[0007] According to the integrated door ring of the present application, by adopting that the A-pillar assembly, the upper side member assembly, the B-pillar assembly, and the sill assembly are each formed by at least two of the first plate, the second plate, the third plate, and the fourth plate, it is possible to achieve a differential thickness design for each part of the A-pillar assembly, the upper side member assembly, the B-pillar assembly, and the sill assembly, so as to specifically strengthen the areas with large forces, while reducing the unnecessary material use in the areas with small forces, thereby achieving the effect of both reducing weight and increasing strength. The first plate, the second plate, the third plate, and the fourth plate with different thicknesses can be welded together into one plate and then stamped at once. Compared with the related art, where additional reinforcing plates need to be added by separate mold opening and spot welding to meet the strength and stiffness requirements, resulting in an increase in weight and cost, the integrated door ring of the present application integrates the first plate, the second plate, the third plate, and the fourth plate with different thicknesses into one component without the need for additional reinforcing plates. In this way, the number of components can be reduced, the mold tooling can be saved, and the double-layer plate overlapping area can be reduced, thereby effectively reducing costs and weights, and further improving the vehicle structure strength, safety performance, and lightweight level.
[0008] According to some embodiments of the present application, the upper side member assembly is formed by the first plate, the second plate, the third plate, and the fourth plate.

The first sub-plate body, the second sub-plate body, the third sub-plate body, and the fourth sub-plate body are sequentially joined in a first direction to define the upper side member assembly.
[0010] In some embodiments, the B-pillar assembly is formed by the first plate and the second plate.
[0011] Further, one of the plurality of second plates is configured as a fifth sub-plate body, and one of the plurality of first plates is configured as a sixth sub-plate body. The fifth sub-plate body is disposed on one side of the third sub-plate body in the width direction and extends away from the third sub-plate body. The sixth sub-plate body is disposed at one end of the fifth sub-plate body away from the third sub-plate body. The sixth sub-plate body and the fifth sub-plate body define the B-pillar assembly.
[0012] According to some embodiments of the present application, the A-pillar assembly and the sill assembly are both formed by splicing the third plate and the fourth plate.
[0013] Further, the fourth plate is configured as a plurality of plates. One of the plurality of fourth plates is configured as a seventh sub-plate body, and the seventh sub-plate body extends in the second direction. One end of the seventh sub-plate body is connected to one end of the first sub-plate body away from the second sub-plate body. The third plate is configured as a plurality of plates. One of the plurality of third plates is configured as an eighth sub-plate body. One end of the eighth sub-plate body is connected to the other end of the seventh sub-plate body. The other end of the eighth sub-plate body is bent and extends in the first direction. The seventh sub-plate body and the eighth sub-plate body define the A-pillar assembly; wherein the second direction intersects the first direction.
[0014] In some embodiments, two of the plurality of fourth plates are respectively configured as a ninth sub-plate body and a tenth sub-plate body. One of the plurality of third plates is configured as an eleventh sub-plate body. One end of the ninth sub-plate body is spliced to the other end of the eighth sub-plate body. The tenth sub-plate body and the eleventh sub-plate body are sequentially spliced to the other end of the ninth sub-plate body and define the sill assembly; wherein one side of the tenth sub-plate body in the width direction is connected to the B-pillar assembly, so that the A-pillar assembly, the upper side member assembly, the B-pillar assembly, and the sill assembly form an annular structure.
[0015] According to some embodiments of the present application, the thicknesses of the second plate, the third plate, the first plate, and the fourth plate decrease in sequence.

[0037] The "plurality" appearing in the present application means two or more (including two).
[0038] Reference is made below Figure 1 and Figure 2 to describe the integrated door ring 1 and the vehicle according to the embodiments of the present application.
[0039] As Figure 1 shown, the integrated door ring 1 according to the embodiment of the first aspect of the present application, the integrated door ring 1 includes: an A-pillar assembly 11, an upper side member assembly 12, a B-pillar assembly 13 and a sill assembly 14 are connected in sequence to define the integrated door ring 1; wherein the A-pillar assembly 11, the upper side member assembly 12, the B-pillar assembly 13 and the sill assembly 14 are each composed of at least two of a first plate 1a, a second plate 1b, a third plate 1c and a fourth plate 1d, and the thicknesses of the first plate 1a, the second plate 1b, the third plate 1c and the fourth plate 1d are different.
[0040] Specifically, the A-pillar assembly 11 and the B-pillar assembly 13 may be opposite in the front-rear direction of the vehicle, the upper side member assembly 12 may be located at the same end of the A-pillar assembly 11 and the B-pillar assembly 13 in the vehicle height direction, the sill assembly 14 may be located at the other end of the A-pillar assembly 11 and the B-pillar assembly 13 in the vehicle height direction, and the A-pillar assembly 11, the upper side member assembly 12, the B-pillar assembly 13 and the sill assembly 14 together define the integrated door ring 1. The A-pillar assembly 11 may be composed of at least two of the first plate 1a, the second plate 1b, the third plate 1c and the fourth plate 1d with different thicknesses according to the positions and different functions of its respective parts, so as to specifically meet the strength requirements of different parts. Similarly, the upper side member assembly 12, the B-pillar assembly 13 and the sill assembly 14 are each composed of at least two of the first plate 1a, the second plate 1b, the third plate 1c and the fourth plate 1d according to the positions of their respective parts and different force characteristics. Exemplarily, the B-pillar assembly 13 is one of the key structures for vehicle side safety and plays a crucial protective role in a collision. The B-pillar assembly 13 may be composed of two of the first plate 1a, the second plate 1b, the third plate 1c and the fourth plate 1d with relatively large thicknesses. The key collision part area in the B-pillar assembly 13 may select the plate with the largest thickness, while the A-pillar assembly 11 generally has a large cavity cross-section and relatively small force, and may be composed of two of the first plate 1a, the second plate 1b, the third plate 1c and the fourth plate 1d with relatively small thicknesses. In this way, cost can be reduced and weight can be reduced.
[0041] According to the integrated door ring 1 of the present application, by adopting that the A-pillar assembly 11, the upper side member assembly 12, the B-pillar assembly 13 and the sill assembly 14 are each composed of at least two of the first plate 1a, the second plate 1b, the third plate 1c and the fourth plate 1d, it is possible to realize the differential thickness design of the respective parts of the A-pillar assembly 11, the upper side member assembly 12, the B-pillar assembly 13 and the sill assembly 14, so as to specifically strengthen the areas with large forces, and at the same time reduce the unnecessary material use in the areas with small forces, thereby achieving the effects of both reducing weight and improving strength. The first plate 1a, the second plate 1b, the third plate 1c and the fourth plate 1d with different thicknesses can be welded together into one plate and then stamped again. Compared with the related art where additional reinforcing plates need to be added by separate die opening and spot welding to meet the strength and stiffness requirements, which results in an increase in weight and cost, the integrated door ring 1 of the present application integrates the first plate 1a, the second plate 1b, the third plate 1c and the fourth plate 1d with different thicknesses into one component without additional reinforcing plates. In this way, the number of components can be reduced, the mold tooling can be saved, and the double-layer plate overlapping area can be reduced, thereby effectively reducing costs and weights, and further improving the vehicle structure strength, safety performance and lightweight level.
[0042] In addition, in some specific embodiments of the present application, the first plate 1a, the second plate 1b, the third plate 1c and the fourth plate 1d are each configured to form a cavity on one side in the thickness direction to improve the structural strength and stiffness of the integrated door ring 1 and enhance the anti-deformation ability.
[0043] As Figure 1 shown, according to some embodiments of the present application, the upper side member assembly 12 is composed of the first plate 1a, the second plate 1b, the third plate 1c and the fourth plate 1d.
[0044] Specifically, the upper side member assembly 12 functions to connect the A-pillar assembly 11 and the B-pillar assembly 13 and is one of the key structures for vehicle collision safety. The force characteristics of different regions of the upper side member assembly 12 are different. Therefore, by composing the upper side member assembly 12 with the first plate 1a, the second plate 1b, the third plate 1c and the fourth plate 1d with different thicknesses, it is possible to realize the layout of plates with different thicknesses corresponding to different regions of the upper side member assembly 12. Specifically, the plate thickness in the key collision safety regions of the upper side member assembly 12 is relatively large, and the thickness of other regions of the upper side member assembly 12 can be relatively small. In this way, the structural performance of the upper side member assembly 12 can be optimized, so that the upper side member assembly 12 can reduce costs and weights while meeting the collision safety performance, and achieve the best performance of the upper side member assembly 12.
[0045] As Figure 1 and Figure 2As shown, according to some embodiments of the present application, the first plate 1a, the second plate 1b, the third plate 1c, and the fourth plate 1d are configured to be multiple, and one of the first plates 1a is configured as the first sub-plate body 12a, one of the second plates 1b is configured as the second sub-plate body 12b, one of the third plates 1c is configured as the third sub-plate body 12c, and one of the fourth plates 1d is configured as the fourth sub-plate body 12d. The first sub-plate body 12a, the second sub-plate body 12b, the third sub-plate body 12c, and the fourth sub-plate body 12d are sequentially joined together in the first direction and define the upper side member assembly 12.
[0046] Specifically, the thicknesses of the first sub-plate body 12a, the second sub-plate body 12b, the third sub-plate body 12c, and the fourth sub-plate body 12d are different. The first sub-plate body 12a, the second sub-plate body 12b, the third sub-plate body 12c, and the fourth sub-plate body 12d are sequentially joined together in the first direction to define the upper side member assembly 12. It can be understood that the upper side member assembly 12 is divided into four regions sequentially arranged in the first direction, and the four regions respectively correspond to the first sub-plate body 12a, the second sub-plate body 12b, the third sub-plate body 12c, and the fourth sub-plate body 12d. By joining the sub-plate bodies, the thickness and strength of different regions of the upper side member assembly 12 can be precisely controlled. For example, in a region with large force, a sub-plate body with a large thickness can be used to improve the bearing capacity of this region, while in a region with small force, a sub-plate body with a small thickness can be used to reduce the weight, thereby achieving precise control and optimization of the structural performance of the upper side member assembly 12, and improving the bearing capacity and safety of the upper side member assembly 12.
[0047] It should be noted that the shapes of the first sub-plate body 12a, the second sub-plate body 12b, the third sub-plate body 12c, and the fourth sub-plate body 12d can be determined according to the overall structure and performance requirements of the vehicle, and the shapes of the first sub-plate body 12a, the second sub-plate body 12b, the third sub-plate body 12c, and the fourth sub-plate body 12d can be the same or different.
[0048] As Figure 1 shown, according to some embodiments of the present application, the B-pillar assembly 13 is formed by joining the first plate 1a and the second plate 1b.
[0049] Specifically, the B-pillar assembly 13 can be formed by splicing a first plate 1a and a second plate 1b. The first plate 1a and the second plate 1b have different thicknesses. Thus, different parts of the B-pillar assembly 13 use plates with different thicknesses, which can meet the functional requirements of different parts (such as collision energy absorption, structural strengthening, etc.). Exemplarily, the upper region of the B-pillar assembly 13 near the upper side member assembly 12 usually has a relatively small cavity cross-section and is more likely to bend during a collision. Therefore, the upper region of the B-pillar assembly 13 near the upper side member assembly 12 can correspondingly adopt the plate with a greater thickness among the first plate 1a and the second plate 1b. The lower region of the B-pillar assembly 13 far from the upper side member assembly 12 has a relatively large cavity cross-section and can correspondingly adopt the plate with a smaller thickness among the first plate 1a and the second plate 1b. Thus, the side collision safety performance requirements of different positions of the B-pillar assembly 13 can be met. On the premise of ensuring the collision safety performance, by reasonably designing the thicknesses of the plate bodies in different regions, the lightweight of the B-pillar assembly 13 can be achieved, which helps to improve the economy and handling performance of the vehicle.
[0050] As Figure 1 and Figure 2 shown, according to some embodiments of the present application, one of the plurality of second plates 1b is configured as a fifth sub-plate body 13a, and one of the plurality of first plates 1a is configured as a sixth sub-plate body 13b. The fifth sub-plate body 13a is disposed on one side of the third sub-plate body 12c in the width direction and extends away from the third sub-plate body 12c. The sixth sub-plate body 13b is disposed at one end of the fifth sub-plate body 13a away from the third sub-plate body 12c. The sixth sub-plate body 13b and the fifth sub-plate body 13a define the B-pillar assembly 13.
[0051] Specifically, one end of the fifth sub-plate body 13a is connected to one side of the third sub-plate body 12c in the width direction. Defined by the vehicle height space, the fifth sub-plate body 13a is disposed on the bottom side of the third sub-plate body 12c. The fifth sub-plate body 13a extends downward away from the third sub-plate body 12c. The sixth sub-plate body 13b can be disposed at the other end of the fifth sub-plate body 13a. The sixth sub-plate body 13b can be in the same extending direction as the fifth sub-plate body 13a. The sixth sub-plate body 13b and the fifth sub-plate body 13a are spliced with each other to define the B-pillar assembly 13. Among them, the fifth sub-plate body 13a defines the upper region of the B-pillar assembly 13 near the upper side member assembly 12, and the sixth sub-plate body 13b defines the lower region of the B-pillar assembly 13 far from the upper side member assembly 12. The fifth sub-plate body 13a and the sixth sub-plate body 13b have different thicknesses, so that the side collision safety performance requirements of different positions of the B-pillar assembly 13 can be met, and the lightweight of the B-pillar assembly 13 can be achieved.
[0052] It should be noted that the fifth sub-plate body 13a has the same thickness as the second sub-plate body 12b, and the fifth sub-plate body 13a and the second sub-plate body 12b are respectively the key collision areas of the B-pillar assembly 13 and the upper side member assembly 12. When the vehicle undergoes a side collision, the two areas defined by the fifth sub-plate body 13a and the second sub-plate body 12b will bear the main impact force. By maintaining the same thickness, it can ensure that these two key areas have sufficient rigidity and strength to effectively disperse and absorb the collision energy, reduce the intrusion of the collision into the occupant compartment, and thus protect the safety of the vehicle occupants; the sixth sub-plate body 13b has the same thickness as the first sub-plate body 12a. The sixth sub-plate body 13b and the first sub-plate body 12a are respectively the collision transition areas of the B-pillar assembly 13 and the upper side member assembly 12. By maintaining the same thickness of the sixth sub-plate body 13b and the first sub-plate body 12a, it helps to optimize the energy transfer in the collision transition area, make the energy transfer more smoothly between the key area and the transition area, reduce stress concentration and sudden energy release, and thus can avoid premature failure of the local structure or the generation of debris that is not conducive to the safety of the occupants, which is beneficial to further improving the collision safety performance.
[0053] As Figure 1 shown, according to some embodiments of the present application, the A-pillar assembly 11 and the sill assembly 14 are both formed by splicing a third plate 1c and a fourth plate 1d.
[0054] Specifically, the A-pillar assembly 11 is connected to the upper side member assembly 12 and is located at one end of the upper side member assembly 12 far from the B-pillar assembly 13 in the extending direction. The A-pillar assembly 11 can be formed by splicing a third plate 1c and a fourth plate 1d, and the thicknesses of the third plate 1c and the fourth plate 1d are different. Thus, different thickness plates can be used for different parts of the A-pillar assembly 11 to meet the functional requirements of different parts (such as connection function, support function, etc.). Exemplarily, the upper region of the A-pillar assembly 11 close to the upper side member assembly 12 usually has a relatively large cavity cross-section and relatively high structural strength. Therefore, a thinner plate among the third plate 1c and the fourth plate 1d can be correspondingly used for the upper region of the A-pillar assembly 11 close to the upper side member assembly 12. And the lower region of the A-pillar assembly 11 far from the upper side member assembly 12 is the key for the dispersion and transfer of collision force and involves the connection part between the A-pillar assembly 11 and the sill assembly 14. Therefore, a thicker plate among the first plate 1a and the second plate 1b can be correspondingly used. Thus, the requirements for the force dispersion and transfer performance of different positions of the A-pillar assembly 11 can be met, the material utilization efficiency can be improved, and the lightweight of the A-pillar assembly 11 can be realized. Similarly, the sill assembly 14 can be formed by splicing a third plate 1c and a fourth plate 1d. The sill assembly 14 is connected to the A-pillar assembly 11 and the B-pillar assembly 13. In the connection regions of the sill assembly 14 with the A-pillar assembly 11 and the B-pillar assembly 13, a thicker plate among the third plate 1c and the fourth plate 1d can be correspondingly used. For other regions of the sill assembly 14, thinner plates among the third plate 1c and the fourth plate 1d can be used to optimize the structural performance of the sill assembly 14 and realize cost reduction and weight reduction of the sill assembly 14.
[0055] As Figure 1 and Figure 2 shown, according to some embodiments of the present application, the fourth plate 1d is configured as multiple, and one of the multiple fourth plates 1d is configured as a seventh sub-plate body 11a. The seventh sub-plate body 11a extends in a second direction. One end of the seventh sub-plate body 11a is connected to one end of the first sub-plate body 12a far from the second sub-plate body 12b. The third plate 1c is configured as multiple, and one of the multiple third plates 1c is configured as an eighth sub-plate body 11b. One end of the eighth sub-plate body 11b is connected to the other end of the seventh sub-plate body 11a. The other end of the eighth sub-plate body 11b is bent and extends in a first direction. The seventh sub-plate body 11a and the eighth sub-plate body 11b define the A-pillar assembly 11; wherein the second direction intersects with the first direction.
[0056] Specifically, the seventh sub-panel body 11a defines a part of the A-pillar assembly 11. The seventh sub-panel body 11a can extend in the second direction, which intersects the first direction (the length direction of the upper side member assembly 12), to meet the shape and force-bearing requirements of the A-pillar assembly 11. The eighth sub-panel body 11b is disposed at one end of the seventh sub-panel body 11a away from the upper side member assembly 12 in the extending direction and defines another part of the A-pillar assembly 11. The other end of the eighth sub-panel body 11b is bent and extends in the first direction to meet the connection requirements between the A-pillar assembly 11 and the sill assembly 14, as well as the connection requirements between the A-pillar assembly 11 and other components such as the door hinge. The different thicknesses and extending directions of the seventh sub-panel body 11a and the eighth sub-panel body 11b can enable the A-pillar assembly 11 to have good flexibility and adaptability while maintaining sufficient rigidity. In this way, it helps to guide the propagation direction of the collision force, improve the side collision safety of the vehicle, and also helps to save the material cost and weight of the A-pillar assembly 11.
[0057] As Figure 1 and Figure 2 shown, according to some embodiments of the present application, two of the plurality of fourth plates 1d are respectively configured as a ninth sub-panel body 14a and a tenth sub-panel body 14b, and one of the plurality of third plates 1c is configured as an eleventh sub-panel body 14c. One end of the ninth sub-panel body 14a is joined to the other end of the eighth sub-panel body 11b, and the tenth sub-panel body 14b and the eleventh sub-panel body 14c are joined to the other end of the ninth sub-panel body 14a in sequence and define the sill assembly 14.
[0058] Among them, one side of the tenth sub-panel body 14b in the width direction is connected to the B-pillar assembly 13, so that the A-pillar assembly 11, the upper side member assembly 12, the B-pillar assembly 13, and the sill assembly 14 form an annular structure.
[0059] Specifically, the ninth sub-panel body 14a, the tenth sub-panel body 14b, and the eleventh sub-panel body 14c can all extend in the first direction. The ninth sub-panel body 14a, the tenth sub-panel body 14b, and the eleventh sub-panel body 14c are sequentially joined together to define the sill assembly 14. Among them, the ninth sub-panel body 14a is connected to one end of the eighth sub-panel body 11b away from the seventh sub-panel body 11a to realize the connection between the sill assembly 14 and the A-pillar assembly 11. One side of the tenth sub-panel body 14b in the width direction is connected to the B-pillar assembly 13 to realize the connection between the sill assembly 14 and the B-pillar assembly 13. It can be understood that the tenth sub-panel body 14b is the key connection point between the sill assembly 14 and the B-pillar assembly 13, which can ensure the stability of the sill assembly 14 during side collisions. And through the formation of the annular structure, the structural rigidity and anti-deformation ability of the entire integrated door ring 1 are improved, so that the entire body side can more stably resist deformation during a collision. The ninth sub-panel body 14a and the eleventh sub-panel body 14c have the same thickness, which is beneficial to improving the production and manufacturing convenience of the sill assembly 14 and helps to reduce the cost and weight of the sill assembly 14.
[0060] As Figure 1 shown, according to some embodiments of the present application, the thicknesses of the second plate 1b, the third plate 1c, the first plate 1a, and the fourth plate 1d decrease in sequence.
[0061] Specifically, in the integrated door ring 1, different plate members bear different functions and force conditions. The second plate 1b is the key collision area in the integrated door ring 1 (located in the upper side member assembly 12 and the B-pillar assembly 13). By setting the thickness of the second plate 1b to be the largest, it can be ensured that the key collision area of the integrated door ring 1 can withstand a relatively large impact force during a collision and serve as the main load-bearing component. As the plate member extends outside the key collision area, its force condition gradually weakens. Therefore, the thicknesses of the third plate 1c (the joint area between the A-pillar assembly 11, the upper side member assembly 12, the B-pillar assembly 13, and the sill assembly 14), the first plate 1a (the collision transition area in the upper side member assembly 12 and the B-pillar assembly 13), and the fourth plate 1d (the general area of the integrated door ring 1) also decrease accordingly. In this way, it helps to realize the reasonable distribution and utilization of materials while maintaining the structural strength. Therefore, by setting the thicknesses of the second plate 1b, the third plate 1c, the first plate 1a, and the fourth plate 1d to decrease in sequence, the integrated door ring 1 can adopt plate members with different thicknesses corresponding to different force characteristics at different positions, thereby achieving a good balance between lightweight and structural strength, effectively reducing the overall weight and production cost of the integrated door ring 1 while ensuring the collision safety performance of the integrated door ring 1.
[0062] Preferably, in some specific embodiments of the present application, the thickness of the second plate 1b is configured to be 1.8 mm to 2.2 mm, the thickness of the third plate 1c is configured to be 1.6 mm to 2.0 mm, the thickness of the first plate 1a is configured to be 1.4 mm to 1.8 mm, and the thickness of the fourth plate 1d is configured to be 1.2 mm to 1.6 mm, so as to ensure that the plate thicknesses in different regions of the integrated door ring 1 are set within a suitable range, so as to ensure a good balance between the light weight and structural strength of the integrated door ring 1.
[0063] In addition, in some specific embodiments of the present application, a plurality of weight-reducing holes are formed at intervals on the first plate 1a, the second plate 1b, the third plate 1c, and the fourth plate 1d, so as to further reduce the weight and further enhance the structural stiffness of the integrated door ring 1.
[0064] As Figure 1 and Figure 2 shown, according to the vehicle of the second aspect embodiment of the present application, the vehicle includes: the integrated door ring 1 described in any one of the above embodiments, and the technical effects generated are the same as those in the above embodiments, and will not be elaborated here.
