In some embodiments, the reinforcing rib 2222 protrudes from the side of the connecting frame plate 2221 relatively close to the front wall support 21, and the gap height between the connecting frame plate 2221 and the front wall support 21 is greater than the gap height between the reinforcing rib 2222 and the front wall support 21; in other embodiments, the reinforcing rib 2222 protrudes from the side of the connecting frame plate 2221 relatively far from the front wall support 21, and the gap height between the connecting frame plate 2221 and the front wall support 21 is less than the gap height between the reinforcing rib 2222 and the front wall support 21, and the second connecting portion 62 can be adapted to connect only the side of the connecting frame plate 2221 relatively far from the front wall support 21, or can be adapted to connect both the side of the connecting frame plate 2221 relatively far from the front wall support 21 and the side of the reinforcing rib 2222 relatively far from the front wall support 21.

[0042] Optionally, the reinforcing rib 2222 protrudes from the side of the connecting frame plate 2221 relatively close to the front wall support 21, and the gap height between the connecting frame plate 2221 and the front wall support 21 is greater than the gap height between the reinforcing rib 2222 and the front wall support 21. In this way, the second connecting portion 62 can be adapted to connect only the side of the connecting frame plate 2221 relatively far from the front wall support 21, and the area of the second connecting portion 62 for connecting the connecting frame plate 2221 can be arranged as a flat surface, thereby realizing stable planar fitting of the second connecting portion 62 and the connecting frame plate 2221, and eliminating the need for subtractive processing of the surface of the second connecting portion 62 to avoid the reinforcing rib 2222, thereby simplifying the structure and modeling of the second connecting portion 62 and reducing the processing steps.

[0043] Referring to Figure 6The reinforcing rib 2222 has a ridge 2222a extending along the Y-axis direction of the vehicle coordinate system. When the reinforcing rib 2222 protrudes from the side of the continuous frame plate 2221 closer to the front wall support 21, the strip-shaped plane or edge of the reinforcing rib 2222 closest to the front wall support 21 forms the ridge 2222a of the reinforcing rib 2222; when the reinforcing rib 2222 protrudes from the side of the continuous frame plate 2221 farther away from the front wall support 21, the strip-shaped plane or edge of the reinforcing rib 2222 farthest away from the front wall support 21 forms the ridge 2222a of the reinforcing rib 2222. The second steering column fixing hole 2224 is provided in the continuous frame plate 2221, and the second connecting portion 62 of the steering column base 60 is fixedly connected to the continuous frame plate 2221 through a fastener and the second steering column fixing hole 2224. The reinforcing rib 2222 can improve the rigidity of the continuous frame plate 2221, and the continuous frame plate 2221 is not easy to bend or twist, thereby serving as a reliable installation basis for the steering column base 60.

[0044] Referring to Figure 6 The reinforcing rib 2222 further comprises a supporting portion 2222b bent at the edge of the ridge 2222a, and the supporting portion 2222b is bently connected between the ridge 2222a and the continuous frame plate 2221 to allow the ridge 2222a and the continuous frame plate 2221 to be spaced apart. Thus, the ridge 2222a, the supporting portion 2222b, and the continuous frame plate 2221 collectively enclose a cavity, so that the reinforcing rib 2222 has a hollow structure. Such an arrangement can help improve the modal properties of the steering column support 22 and even the instrument panel cross beam assembly.

[0045] Referring to Figure 6 The reinforcing rib 2222 has a rib groove 2223 extending along the length direction of the cross beam 11. Such an arrangement makes the structure of the reinforcing rib 2222 more complex, the ridge 2222a has higher strength and rigidity, and the reinforcing rib 2222 itself is not easy to bend or twist. Therefore, the ability of the reinforcing rib 2222 to help improve the rigidity of the continuous frame plate 2221 is further improved.

[0046] Referring to Figures 5-6 Further, the proximal end of the steering column support 22 further comprises a side protruding plate 224 extending outwardly and protruding from the side of the second steering column mounting portion 222 and fixedly fitted to the side of the cross beam 11. The outward protrusion of the side protruding plate 224 means that the side protruding plate 224 extends and protrudes from the side of the second steering column mounting portion 222 in a direction away from the distal end of the frame 223 and close to the driver's cabin. Specifically, the side protruding plate 224 can extend outwardly and protrude from the side of the continuous frame plate 2221. The number of side protruding plates 224 can be one or more. Such an arrangement makes the steering column support 22 and the cross beam unit 10 more integrated, and the cross beam unit 10 can share the force acting on the steering column support 22 from the vehicle body front wall and the steering column assembly.

[0047] Further, referring to Figures 3-6The connecting position of the first steering column mounting portion 12 and the cross beam 11 is a first connection position, the first steering column mounting portion 12 protrudes from and is welded to the side of the cross beam 11, and a welding seam distributed at the first connection position is formed between the first steering column mounting portion 12 and the cross beam 11; the connecting position of the steering column support 22 and the cross beam 11 includes a second connection position between the side protruding plate 224 and the side of the cross beam 11 and between the proximal end of the frame 223 and the side of the cross beam 11, the side protruding plate 224 and the side of the cross beam 11 are welded and fixed, and the proximal end of the frame 223 and the side of the cross beam 11 are welded and fixed, and the first connection position and the second connection position are located on opposite sides of the cross beam 11. In this way, the force acting on the cross beam 11 by the first steering column mounting portion 12 and the second steering column mounting portion 222 is more dispersed, and the local overload of the cross beam 11 caused by local stress concentration of the cross beam 11 can be avoided, thereby effectively improving the load capacity of the cross beam 11. On this basis, further, the proximal end of the front wall support 21 is welded to the cross beam 11.

[0048] Optionally, the front wall support 21 is a single non-detachable support, the steering column support 22 is a single non-detachable support, and the reinforcing rib 2222 is a non-detachable part of the steering column support 22. The front wall support 21 and the steering column support 22 form a hollow cavity, and in this way, the modal of the support unit 20 is improved. Preferably, the front wall support 21 can be a single non-detachable structure formed by welding a plurality of plates or can be an integrally formed plate, and the steering column support 22 can be a single non-detachable structure formed by welding a plurality of plates or can be an integrally formed plate.

[0049] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not contradict each other, they should be considered within the scope of the present disclosure.

[0050] Those skilled in the art should understand that the above embodiments are only used to illustrate the present application, but not as a limitation of the present application, and any appropriate changes and variations made to the above embodiments within the spirit and principles of the present application fall within the scope of the present application.
