[0035] In some embodiments, a first projection welding stud 6 is projection welded on one side of the column back plate 3, and the first projection welding stud 6 is connected to the steering column after passing through the column back plate 3 and the column mounting plate 2 in sequence. The first projection welding stud 6 is arranged so that the reinforcement beam body 1, the column back plate 3, the first projection welding stud 6 and the column mounting plate 2 form a first closed reinforcement structure 300, thereby improving the rigidity and anti-deformation ability of the reinforcement beam body 1.

[0036] There may be a plurality of first projection welding studs 6 . For example, there are two first projection welding studs 6 along the vehicle width direction.

[0037] In some embodiments, a second projection weld stud 7 is projection welded on one side of the column mounting bracket 4, and the second projection weld stud 7 sequentially passes through the column mounting bracket 4 and the column mounting plate 2. The second projection weld stud 7 is provided and connected to the steering column after passing through the column back plate 3 and the column mounting plate 2, so that the reinforcement beam body 1, the column mounting bracket 4, the second projection weld stud 7 and the column mounting plate 2 form a second closed reinforcement structure 400, thereby improving the rigidity and anti-deformation ability of the reinforcement beam body 1.

[0038] There are two column mounting brackets 4 , and the two column mounting brackets 4 are arranged along the width direction of the vehicle. Corresponding to the column mounting brackets 4 , two second projection welding studs 7 are provided.

[0040] Furthermore, the column mounting plate 2 and the reinforcement beam body 1 form a closed structure, thereby improving the rigidity of the reinforcement beam body 1 and further improving the installation strength of the steering column.

[0041] In some embodiments, the connecting frame 5 includes a HUD mounting bracket 51. The head-up display is referred to as HUD, which is also called a head-up display system. The HUD can project the vehicle's current speed, navigation and other information onto the photoelectric display device on the windshield, forming an image in front of the windshield. The driver can see the navigation and vehicle speed information without turning his head or lowering his head. The HUD mounting bracket 51 is used to install the HUD, and the HUD mounting bracket 51 is installed on one side of the reinforcing beam body 1. The HUD mounting bracket 51 is provided with a mounting hole 18, and the HUD determines the installation position through the mounting hole 18 and is installed on the HUD mounting bracket 51 through the mounting hole 18.

[0042] In some embodiments, Figure 4 As shown, the connection frame 5 also includes a back plate reinforcement bracket 52, and the HUD mounting bracket 51, the back plate reinforcement bracket 52, the column back plate 3 and the reinforcement beam body 1 are sequentially connected to form a closed structure. The closed structure realizes closed-loop reinforcement.

[0043] In some embodiments, Figure 4 and Figure 5 As shown, the HUD mounting bracket 51 is connected to the front of the vehicle through the first fastener 8, and the first fastener 8 passes through the front of the vehicle and the HUD mounting bracket 51 in sequence. The first fastener 8 is used to fasten the front of the vehicle and the HUD mounting bracket 51, and the entire instrument panel reinforcement beam is connected to the front of the vehicle. The first fastener 8 is installed from the head of the vehicle to the rear of the vehicle, so that a avoidance opening 9 corresponding to the first fastener 8 is opened at one end of the back panel reinforcement bracket 52 close to the HUD mounting bracket 51. The avoidance hole avoids the first fastener 8, which is conducive to reducing the space occupied by the instrument panel reinforcement beam along the height direction of the vehicle. Exemplarily, two first fasteners 8 are provided, and two avoidance openings 9 are correspondingly provided, and the avoidance openings 9 are U-shaped.

[0044] Providing the avoidance opening 9 on the back plate reinforcement bracket 52 will cause strength loss to the back plate reinforcement bracket 52. In some embodiments, a reinforcement frame 10 is provided on one side of the back plate reinforcement bracket 52 near the avoidance opening 9. The reinforcement frame 10 is used to compensate for the strength loss of the back plate reinforcement bracket 52 caused by the avoidance opening 9. The reinforcement frame 10 and the back plate reinforcement bracket 52 form a third reinforcement cavity 500.

[0045] The back panel reinforcement bracket 52 is provided with a weight-reducing hole 11, which is conducive to achieving lightweight of the instrument panel reinforcement beam. The shape of the weight-reducing hole 11 can be adapted to the contour of the back panel reinforcement bracket 52. Exemplarily, the shape of the back panel reinforcement bracket 52 is a trapezoid, and the shape of the weight-reducing hole 11 is set to be a trapezoid.

[0046] In some embodiments, one end of the back plate reinforcement bracket 52 has a welding bracket 12, and the welding bracket 12 is welded to the HUD mounting bracket 51 from a first direction and a second direction. The welding bracket 12 has a first connection portion 121 and a second connection portion 122, wherein the first direction is the vehicle height direction, and the second direction is the vehicle length direction, the first connection portion 121 extends outward along the back plate reinforcement bracket 52, and the first connection portion 121 and the second connection portion 122 are respectively connected to the HUD mounting bracket 51 from two directions, thereby improving the connection reliability between the HUD mounting bracket 51 and the back plate reinforcement bracket 52.

[0047] Preferably, if Figure 6 As shown, the first connection portion 121 is welded to the top of the HUD mounting bracket 51, and there is a weld bead 20 between the first connection portion 121 and the HUD mounting bracket 51; the second connection portion 122 is welded to the side of the HUD mounting bracket 51 facing the front of the vehicle, and there are two weld bead 20 between the second connection portion 122 and the HUD mounting bracket 51. The HUD mounting bracket 51 and the back plate reinforcement bracket 52 are connected by multiple weld bead 20, which can improve the connection strength between the two.

[0048] In some embodiments, Figure 4 As shown, the left and right sides of the back plate reinforcement bracket 52 have connection flanges 13, and the HUD mounting bracket 51 has a mounting groove 14, and the connection flanges 13 match the mounting groove 14. The connection flanges 13 extend into the mounting groove 14, so that the connection flanges 13 and the groove wall of the mounting groove 14 form a closed loop structure, thereby improving the connection strength of the back plate reinforcement bracket 52 and the HUD mounting bracket 51.

[0049] In some embodiments, Figure 7As shown, the side wall connecting bracket 15 is installed at both ends of the reinforcing beam body 1. The side wall connecting bracket 15 is connected to the vehicle side wall through the second fastener 16 to realize the connection between the entire instrument panel reinforcing beam and the vehicle side wall. The side wall connecting bracket 15 has a first mounting portion 151 and a second mounting portion 152. The first mounting portion 151 is connected to the reinforcing beam body 1, and the second mounting portion 152 is connected to the vehicle side wall. Further, a side wall reinforcing bracket 17 is arranged outside the side wall connecting bracket 15, wherein the outside of the side wall connecting bracket 15 refers to the side facing the outside of the vehicle. The side wall reinforcing bracket 17 is arranged between the first mounting portion 151 and the second mounting portion 152 to improve the strength of the side wall connecting bracket 15. Since a through hole for installing the second fastener 16 is provided on the side wall connecting bracket 15, the through hole will cause strength loss to the side wall connecting bracket 15, so one end of the side wall reinforcing bracket 17 is arranged close to the second fastener 16 to compensate for the strength loss.

[0050] The first mounting portion 151 is connected to the vehicle side wall through the latch 19. When the side wall connecting bracket 15 is mounted to the vehicle side wall, the position of the side wall connecting bracket 15 and the vehicle side wall is first limited by the latch 19 to preliminarily determine the mounting position of the side wall connecting bracket 15, and then the side wall connecting bracket 15 is fixed to the vehicle side wall through the second fasteners 16 provided on both sides of the latch 19. The latch 19 can quickly determine the relative position of the vehicle body side wall and the side wall connecting bracket 15, thereby improving the mounting efficiency.

[0051] A second embodiment of the utility model provides a vehicle, comprising the above-mentioned instrument panel reinforcement beam.

[0052] The instrument panel reinforcement beam comprises a reinforcement beam body 1, wherein the reinforcement beam body 1, the connection frame 5 and the column back plate 3 are sequentially connected to form a closed structure, which is conducive to strengthening the strength of the reinforcement beam body 1. A column mounting plate 2 is installed at the bottom of the reinforcement beam body 1, and the side of the column mounting plate 2 facing the front of the vehicle is connected to the column back plate 3 to form a first reinforcement cavity 100, and the side of the column mounting plate 2 facing the rear of the vehicle is connected to the column mounting bracket 4 to form a second reinforcement cavity 200. The first reinforcement cavity 100 and the second reinforcement cavity 200 increase the rigidity of the reinforcement beam body 1, thereby increasing the connection strength between the reinforcement beam body 1 and the steering column, and improving the stability of the steering wheel.
