[0036] The anti-collision beam body 10 is along the length direction of the vehicle (ie Figure 1 The anti-collision beam body 10 includes a first beam body 11 and a second beam body 12, extending in the longitudinal direction of the vehicle (ie, Figure 1 In the X direction shown in the figure), the first beam body 11 is located in front of the second beam body 12, and the first beam body 11 and the second beam body 12 are connected. The connection method of the first beam body 11 and the second beam body 12 can be a direct connection, or the connection method of the first beam body 11 and the second beam body 12 can be an indirect connection. As some embodiments of the present application, the connection method of the first beam body 11 and the second beam body 12 is a direct connection. The connection method of the first beam body 11 and the second beam body 12 can be but not limited to welding, clamping, etc. For example, the first beam body 11 and the second beam body 12 are connected by welding. As some embodiments of the present application, the connection method of the first beam body 11 and the second beam body 12 is an indirect connection. The anti-collision beam body 10 also includes: a third beam body 13, and the third beam body 13 is connected between the first beam body 11 and the second beam body 12, so that the first beam body 11 and the second beam body 12 are indirectly connected. The anti-collision beam body 10 can also be an integrally formed part.

[0037] like Figure 2 As shown, the cross section of the first beam body 11 is circular. It can be understood that the cross section of the first beam body 11 is a completely closed circular arc surface, similar to the shape of the letter O, as shown in FIG. Figure 4 As shown, the second beam body 12 includes: a first plate body 121 and a second plate body 122, the first plate body 121 is a flat plate 123, and the second plate body 122 is an arc-shaped plate 124, along the height direction of the vehicle (ie Figure 1 The first plate 121 has two opposite ends, and the arc-shaped plate 124 also has two opposite ends. The two ends of the first plate 121 are respectively connected to the two ends of the second plate 122, so that the second beam 12 is along the width direction of the vehicle (i.e. Figure 1 The cross-section of the plane (the Y direction shown) is constructed to be similar to the shape of the letter D.

[0038] like Figure 1 and Figure 3As shown, the anti-collision beam body 10 further includes: a third beam body 13 , which is connected between the first beam body 11 and the second beam body 12 , and the cross section of the third beam body 13 is elliptical.

As some embodiments of the present application, the first beam body 11 and the third beam body 13 are connected by thermoforming. As some embodiments of the present application, the second beam body 12 and the third beam body 13 are connected by thermoforming. This arrangement can ensure that the transition connection between the first beam body 11, the second beam body 12 and the third beam body 13 is smooth, so that the anti-collision beam body 10 forms a reliable force transmission path and can meet the collision requirements.

[0040] As some embodiments of the present application, the first beam body 11, the second beam body 12 and the third beam body 13 are integrally formed, that is, the anti-collision beam body 10 is constructed as an integrally formed part, and the integrally formed part has good structural strength. By integrally forming the first beam body 11, the second beam body 12 and the third beam body 13, the connection reliability of the first beam body 11, the second beam body 12 and the third beam body 13 can be improved, and the probability of the anti-collision beam body 10 breaking can be reduced.

[0041] The third beam body 13 is connected between the first beam body 11 and the second beam body 12 . The cross section of the third beam body 13 is elliptical. It can be understood that the cross section of the third beam body 13 is a completely closed elliptical arc surface, similar to the shape of the number 0.

[0042] It should be noted that the circular cross-section of the first beam body 11 can withstand the main collision force, and the cross-section of the second beam body 12 is similar to the letter D to maintain stability to reduce the risk of large-scale collapse of the anti-collision beam body 10.

[0045] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the flat plate 123 is located on the side of the curved plate 124 facing outward from the vehicle, that is, along the width direction of the vehicle (i.e. Figure 1 The flat plate 123 is located on the side of the curved plate 124 facing the outside of the vehicle, and the two ends of the flat plate 123 are respectively connected to the two ends of the curved plate 124, and the concave side of the curved plate 124 is the side facing the outside of the vehicle. Such an arrangement can make the second beam body 12 reasonably designed and can make the second beam body 12 adapt to the installation space of the vehicle door. In addition, by making the flat plate 123 located on the side of the curved plate 124 facing the outside of the vehicle, the risk of interference between the first plate body 121 and the outer panel of the vehicle door can be reduced, which is beneficial to improving the reliability and structural rationality of the anti-collision beam assembly 100.

[0046] In some embodiments of the present invention, the anti-collision beam body 10 is constructed as an integrally formed part, that is, the first beam body 11, the second beam body 12 and the third beam body 13 are integrally formed, and the integrally formed part has good structural strength. By integrally forming the first beam body 11, the second beam body 12 and the third beam body 13, the connection reliability between the first beam body 11 and the second beam body 12, and the second beam body 12 and the third beam body 13 can be improved, and the probability of the anti-collision beam body 10 breaking can be reduced.

That is to say, the first connecting plate 20 and the second connecting plate 30 are arranged in the installation space defined by the inner door panel and the outer door panel, and the first connecting plate 20 and the second connecting plate 30 are both connected to the inner door panel.

[0050] As some embodiments of the present application, the first connecting plate 20 and the second connecting plate 30 are both connected to the door inner panel by spot welding. As some embodiments of the present application, the welding points between the first connecting plate 20 and the door inner panel are arranged at three locations, and the welding points between the second connecting plate 30 and the door inner panel are arranged at three locations. In addition, two of the welding points between the first connecting plate 20 and the door inner panel are arranged symmetrically along the axis of the anti-collision beam body 10, and the other welding point is arranged between the two welding points and is aligned with the anti-collision beam body 10 along the length direction of the vehicle (i.e., Figure 1 The second connecting plate 30 and the door inner panel welding points are symmetrically arranged along the axis of the anti-collision beam body 10, and the other welding point is arranged between the two welding points and is aligned with the anti-collision beam body 10 along the length direction of the vehicle (i.e. Figure 1 This arrangement can improve the connection strength between the first and second connecting plates 20, 30 and the door inner panel, and is conducive to ensuring that the force transmission during the collision is always maintained at the main cross-sectional area of the anti-collision beam body 10. It can also ensure that the welding position bears more force during the collision, thereby improving the uniformity of the local force during the collision.

[0051] As some embodiments of the present application, the first connecting plate 20 and the second connecting plate 30 are arranged at equal distances from the rounded corners of the vehicle door inner panel.
