[0002] At present, automobiles are constantly developing towards electrification, networking, and intelligence, which has brought a qualitative improvement to people's travel methods. Although various active safety technologies equipped in vehicles are constantly reducing the probability of automobile accidents, passive structural safety is still the most basic requirement of vehicles, especially the body safety, which is the last line of defense to protect drivers and passengers. In the process of electrification of automobiles, lightweighting is an important factor in improving vehicle endurance, but lightweighting of the body is not a simple weight reduction, and must be based on ensuring the strength and safety performance of the body. Under the demand for body safety and lightweighting, one-piece hot-formed door rings came into being.

[0003] However, in order to improve the comfort and safety of the driver's front vision, the A-pillar obstacle angle should be as small as possible, which means that the body door ring should be as thin as possible in the A-pillar area. However, when a vehicle is in a head-on collision, the A-pillar is a key component for frontal force transmission, protecting the passenger compartment from deformation and passengers from injury. Especially for off-road vehicles, the A-pillar is more upright, and the head-on force transmission effect is not good, and the A-pillar and the upper side beam are easily bent.

[0020] The side enclosure also includes: more than one roof cross beam, which is distributed at intervals along the length direction of the vehicle body and is connected to the upper side beam of the door ring body.

DETAILED DESCRIPTION

[0043] In order to make the technical personnel in the technical field to which the present application belongs to understand the present application more clearly, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0044] In the prior art, due to the slimness of the upper side beam, when the vehicle is hit, the upper side beam near the A-pillar bears a greater collision load, causing the upper side beam near the A-pillar to easily produce a larger deformation. The upper side beam near the A-pillar bends toward the inside of the vehicle, occupying a larger space inside the vehicle, affecting the safety of the occupants.

[0045] In order to solve the above technical problems, the present application provides a vehicle body door ring structure and a vehicle. It should be noted that in the art, the length direction of a vehicle is usually referred to as the X direction or longitudinal direction, the width direction of a vehicle is called the Y direction or transverse direction, and the height direction of a vehicle is called the Z direction or vertical direction. The interpretation of the relevant directional expressions in the following embodiments can refer to the above content.

[0046] See also Figure 1 and Figure 2 According to a first embodiment of the present application, a vehicle body door ring structure 100 is provided. The vehicle body door ring structure 100 includes a door ring body 110 and a first tube beam 120. The door ring body 110 includes an upper side beam 111, a lower side beam 112 and at least two pillars. The at least two pillars are spaced apart along the length direction of the vehicle body, and the two ends of the pillars are respectively connected to the upper side beam 111 and the lower side beam 112 to form a ring structure. The upper side beam 111 is provided with a cavity, and the cavity extends from the first pillar to the last pillar along the axial direction of the upper side beam 111; the first tube beam 120 is located in the cavity and is connected to the upper side beam 111 and each pillar.

[0047] The present application effectively improves the conditions of the A-pillar 113 and the upper side beam 111 without increasing the size of the cavity by arranging the first tube beam 120 inside the cavity of the upper side beam 111. When the vehicle is hit, the first tube beam 120 arranged inside the cavity of the upper side beam 111 can bear a part of the collision load, thereby reducing the collision load transmitted to the upper side beam 111 and reducing the deformation of the upper side beam 111 bending into the passenger compartment, so that the deformation of the A-pillar 113 and the upper side beam 111 meets the requirements of the collision, further improving the strength and bending resistance of the A-pillar 113 and the upper side beam 111, and ensuring the space of the passenger compartment and the safety of the passengers in the vehicle.

[0048] As attached Figure 1 and attached Fig.12 As shown, in some embodiments, there are three pillars, namely A-pillar 113, B-pillar 114 and C-pillar 115. A-pillar 113, B-pillar 114 and C-pillar 115 are spaced apart along the length direction of the vehicle body, and the two ends of A-pillar 113, B-pillar 114 and C-pillar 115 are respectively connected to the upper side beam 111 and the lower side beam 112 to form a ring structure.

[0049] As attached Figure 1 and attached Fig.12 As shown, the upper side beam 111 of the present application is provided with a cavity for arranging the first tube beam 120 in the cavity, wherein the first tube beam 120 extends along the A-pillar 113 to the C-pillar 115, and runs through the entire upper side beam 111. The first tube beam 120 extends along the A-pillar 113 to the C-pillar 115, that is, the bending strength of the upper side beam 111, the A-pillar 113, the B-pillar 114 and the C-pillar 115 can be improved, rather than only improving the strength of the upper side beam 111 locally. In some embodiments, the first tube beam 120 can be made of hot-formed high-strength steel, and the tensile strength can reach 1500MPa to 2000MPa, which can well meet the strength requirements of the vehicle when it is hit head-on or rolled over. In other embodiments, the first tube beam 120 can be made of hot expansion technology, and its cross-sectional size is designed according to the shape of the door ring cavity, and is designed from front to back. That is, without increasing the size of the cavity of the roof side beam 111, the first tube beam 120 can be arranged inside the cavity of the roof side beam 111, thereby improving the bending strength of the roof side beam 111. The first tube beam 120 can disperse a part of the impact force when subjected to impact, and can better disperse the sudden impact force; in addition, the first tube beam 120 can also absorb a part of the energy. When subjected to a severe impact, the first tube beam 120 can disperse the impact force more evenly, thereby reducing the impact force of the roof side beam 111.

[0050] Therefore, the present application effectively improves the conditions of the door ring A-pillar 113 and the upper side beam 111 without increasing the size of the cavity by arranging the first tube beam 120 inside the cavity of the upper side beam 111. In addition, the tube beam is designed to fit well with the inner cavity of the door ring, and the cross-sectional shape and size can be optimized, further improving the bending resistance of the door ring in the A-pillar 113 area.

[0051] As attached Fig.11 and attached Fig.14As shown, in some embodiments, the first tube beam 120 includes a first tube section that fits with the upper side beam 111 and a second tube section that is spaced apart from the upper side beam 111; since the first tube beam 120 needs to be designed with a profile, it is ensured that the first tube beam 120 can fit with the cavity of the upper side beam 111. The cross-section of the cavity of the upper side beam 111 is relatively large in some areas, and relatively small in some areas. Therefore, in order to ensure that the first tube beam 120 is arranged in the cavity of the upper side beam 111, the first tube beam 120 is arranged in the cavity of the upper side beam 111, and the cross-sectional area of ​​the first tube beam 120 is smaller than the cross-sectional area of ​​the cavity of the upper side beam 111. In order to ensure that the cross-sectional area of ​​the first tube beam 120 does not change too much, the first tube beam 120 will fit with the upper side beam 111 in some areas, and there will be a gap between the first tube beam 120 and the upper side beam 111 in some areas.

[0052] As attached Figure 1 As shown, in some embodiments, along the length direction of the vehicle, the circumference of the cross section of the first tube beam 120 from the front to the rear of the vehicle varies in the range of 0-15%, following the cavity design of the upper side beam 111. This can ensure that the first tube beam 120 can be designed according to the cavity of the upper side beam 111 so that it can be installed in the cavity of the upper side beam 111, and the strength of the first tube beam 120 can also be improved. If the circumference of the cross section of the first end and the second end of the first tube beam 120 varies greatly, the strength of the first tube beam 120 will be weakened, which is not conducive to improving the overall strength. Therefore, the circumference of the cross section of the first end and the second end of the first tube beam 120 varies slightly, which can ensure the strength of the first tube beam 120.

[0053] In some embodiments, the first tube beam 120 is an internal hollow structure, and the first tube beam 120 can be better designed to follow the cavity shape of the upper side beam 111, thereby achieving the purpose of reducing weight while ensuring strength.

[0054] As attached Fig.14 As shown, since there is still a gap between the second tube section of the second tube beam 210 and the upper side beam 111, in some embodiments, the vehicle body door ring structure 100 further includes a bracket 130 connected to the second tube section, and the second tube section is connected to the upper side beam 111 through the bracket 130. That is, it can ensure that the first tube beam 120 can be designed in accordance with the shape and the strength of the first tube beam 120 is ensured, and at the same time, the area where the first tube beam 120 cannot be directly connected to the upper side beam 111 is connected through the bracket 130, thereby improving the strength of the upper side beam 111.

[0055] As attached Figure 2 , Attachment Figure 4 and attached Fig.14As shown, in some embodiments, the bracket 130 includes an upper bracket 131 and a lower bracket 132, and the upper bracket 131 and the lower bracket 132 enclose a first installation cavity, and the upper bracket 131 and the lower bracket 132 partially overlap and are connected, and the overlapping area is connected to the column. The upper bracket 131 and the lower bracket 132 partially overlap, and the overlapping area can be connected by welding to ensure the connection strength. The upper bracket 131 and the lower bracket 132 enclose the first installation cavity, which can achieve the purpose of weight reduction while ensuring that the second pipe section of the first pipe beam 120 can be connected to the upper side beam 111. One end of the upper bracket 131 is connected to the first tube beam 120, which can be connected by welding, and the other end of the upper bracket 131 is bent toward the lower bracket 132; one end of the lower bracket 132 is connected to the first tube beam 120, which can be connected by welding, and the other end of the lower bracket 132 is bent toward the upper bracket 131 so as to overlap with a bent section of the upper bracket 131; it can be understood that the upper bracket 131 and the lower bracket 132 are mounted on the first tube beam 120, and the first installation cavity formed by the upper bracket 131 and the lower bracket 132 facilitates the connection of the first tube beam 120 with other surrounding parts through the bracket 130, plays a role in force transmission, and thus improves the strength.

[0056] As attached Figure 5 , Attachment Figure 6 , Attachment Figure 7 , Attachment Figure 8 , Attachment Fig. 9 , Attachment Fig.10 , Attachment Fig.11 As shown, in some embodiments, the cross-section of the first tube beam 120 is an irregularly shaped closed structure, that is, it can better fit with the cavity and improve the strength; in other embodiments, the Z-direction dimension of the cross-section of the first tube beam 120 is the largest. The cross-section of the first tube beam 120 of the present application is irregular. Compared with regular tube beams such as round and square, the first tube beam 120 of the present application can not only better adapt to the cavity of the upper side beam 111, but also can achieve the maximum Z-direction dimension of the cross-section of the first tube beam 120, further improve the tensile strength in the Z direction, and improve the strength.

[0057] As attached Figure 7 As shown, in some embodiments, the first tube beam 120 is provided with a plurality of avoidance holes 121 and / or electrophoresis holes. The electrophoresis holes can provide channels for electrophoresis fluid to pass through between the sheet metals, thereby improving the electrophoresis performance; the avoidance holes 121 can locally prevent the components from interfering with each other in position.

[0058] As attached Figure 5 , Attachment Figure 6 , Attachment Figure 7 , Attachment Figure 8 , Attachment Fig. 9 , Attachment Fig.10 , Attachment Fig.11As shown, in some embodiments, there are three pillars, namely, A-pillar 113, B-pillar 114, and C-pillar 115; the first tube beam 120 is welded to the upper side beam 111 by two weldings 119; the upper side beam 111 is provided with three groups of plug welding holes, namely, a first group of plug welding holes 116, a second group of plug welding holes 117, and a third group of plug welding holes 118, the first group of plug welding holes 116 is located near the A-pillar 113, the second group of plug welding holes 117 is located near the front of the B-pillar 114, and the third group of plug welding holes 118 is located between the B-pillar 114 and the C-pillar 115.

[0059] As attached Figure 5 , Attachment Figure 6 and attached Figure 7 As shown, in some embodiments, the first group of plug welding holes 116 may include at least 2 plug welding holes, which may be 2 plug welding holes, 3 plug welding holes, 4 plug welding holes or 5 plug welding holes. In the region of the first group of plug welding holes 116, the first tube beam 120 and the upper side beam 111 may be welded by two weldings 119. The first group of plug welding holes 116 are distributed between the A-pillar 113 and the B-pillar 114 and are close to the A-pillar 113. Since the outer surface of the upper side beam 111 is not in the same plane, but in a three-dimensional shape, in order to ensure the stability of the welding between the first tube beam 120 and the upper side beam 111, the plug welding holes may be staggered on the side elevation and the upper surface of the upper side beam 111, thereby ensuring that the first tube beam 120 and the side elevation and the upper surface of the upper side beam 111 have welding points, so that the first tube beam 120 and the upper side beam 111 are connected more stably. In some embodiments, the first group of plug welding holes 116 may include 4 plug welding holes, and two adjacent plug welding holes are staggered up and down. Ensure that the first tube beam 120 is connected to both the side surface and the upper surface of the upper side beam 111 .

[0060] As attached Figure 5 , Attachment Figure 8 and attached Fig. 9As shown, in some embodiments, the second group of plug welding holes 117 may include at least 2 plug welding holes, which may be 2 plug welding holes, 3 plug welding holes, 4 plug welding holes or 5 plug welding holes. In the area of ​​the second group of plug welding holes 117, the first tube beam 120 and the upper side beam 111 may be welded by two weldings 119. The second group of plug welding holes 117 are distributed between the A-pillar 113 and the B-pillar 114 and are close to the B-pillar 114. Since the outer surface of the upper side beam 111 is not in the same plane, but in a three-dimensional shape, in order to ensure the stability of the welding of the first tube beam 120 and the upper side beam 111, the plug welding holes may be staggered on the side elevation and the upper surface of the upper side beam 111, thereby ensuring that the first tube beam 120 and the side elevation and the upper surface of the upper side beam 111 have welding points, so that the first tube beam 120 and the upper side beam 111 are connected more stably. In some embodiments, the second group of plug welding holes 117 may include 3 plug welding holes, and two adjacent plug welding holes are staggered up and down. Ensure that the first tube beam 120 is connected to both the side surface and the upper surface of the upper side beam 111 .

[0061] As attached Figure 5 , Attachment Fig.10 and attached Fig.11 As shown, in some embodiments, the third group of plug welding holes 118 may include at least 2 plug welding holes, which may be 2 plug welding holes, 3 plug welding holes, 4 plug welding holes or 5 plug welding holes. In the area of ​​the third group of plug welding holes 118, the first tube beam 120 and the upper side beam 111 may be welded by two weldings 119. The third group of plug welding holes 118 are distributed between the B-pillar 114 and the C-pillar 115 and are close to the C-pillar 115. Since the outer surface of the upper side beam 111 is not in the same plane, but in a three-dimensional shape, in order to ensure the stability of the welding between the first tube beam 120 and the upper side beam 111, the plug welding holes may be staggered on the side elevation and the upper surface of the upper side beam 111, thereby ensuring that the first tube beam 120 and the side elevation and the upper surface of the upper side beam 111 have welding points, so that the first tube beam 120 and the upper side beam 111 are connected more stably. In some embodiments, the third group of plug welding holes 118 may include 3 plug welding holes, and two adjacent plug welding holes are staggered up and down. Ensure that the first tube beam 120 is connected to both the side surface and the upper surface of the upper side beam 111 .

[0062] Thus, two adjacent plug welding holes of each group of plug welding holes are arranged in an up-and-down staggered manner and distributed on the side elevation and the upper surface of the upper side beam 111, so that the first tube beam 120 is more firmly connected to the upper side beam 111. The first tube beam 120 is connected to the upper side beam 111 by staggered plug welding, and the connection strength of multi-faceted staggered welding is better and more stable, so that the first tube beam 120 and the upper side beam 111, that is, the upper side beam 111 and the door ring body 110, form a whole, and have better anti-bending performance.

[0063] In a second aspect of the present application, a vehicle is provided, as shown in FIG. Fig.12As shown, the side wall 200 of the vehicle includes: the above-mentioned vehicle body door ring structure 100 and the second tube beam 210, the first tube beam 120 is provided with a first connection part, the second tube beam 210 is connected to the rear end of the first tube beam 120, the second tube beam 210 is provided with a second connection part corresponding to the first connection part, the first connection part overlaps and is connected with the second connection part, that is, the first tube beam 120 and the second tube beam 210 can be connected.

[0064] As attached Fig.16 As shown, in some embodiments, the second tube beam 210 and the first tube beam 120 are both hollow structures, and the second tube beam 210 is provided with a second connection portion, and the first connection portion overlaps and is connected with the second connection portion. The inner diameter of the second tube beam 210 at the position where the second tube beam 210 is close to the first tube beam 120 is greater than the inner diameter of the first tube beam 120. Ensure that the first tube beam 120 and the second tube beam 210 are connected, so that the first tube beam 120 located at the front of the upper side beam 111 and the second tube beam 210 located at the rear of the upper side beam 111 are connected front and back.
